I have a gym 5 minutes away from home, where I have occasional troubles (like being locked out at night or membership issues) but it’s very nice and comfy to get to, and I have a gym 15 minutes away where I haven’t been but wouldn’t expect these problems. It should be same level. I already paid 50$ for first gym, while paying only 5$ for second gym. I have access to both. Where should I be going? Time is valuable.

GPT-5.4

Vote: First

I’m keeping my vote for A. The decisive factor is still the large, guaranteed commute difference: 5 minutes versus 15 minutes each way means about 20 extra minutes per visit for the second gym. If time is valuable, that repeated cost matters more than a problem that is described as only occasional. Claude’s reliability argument is the strongest case for B, but it depends on the issues being frequent or severe enough to regularly ruin workouts. The prompt does not say that; it says occasional troubles. On the facts given, a certain 20-minute penalty every visit is a bigger expected cost than sporadic disruptions. The other A arguments reinforce the key practical point: lower friction usually leads to better consistency. A gym that is very easy and comfy to reach is the one you are most likely to use regularly. The money difference should not drive the choice now because both memberships are already accessible. Going forward, optimize for expected time and adherence, which still favors the first gym unless the access problems become common.

Claude Opus 4.6's argument about reliability costs is compelling and better grounded in the search results than my previous reasoning. The search results show that location is the primary factor, but they also emphasize that gym success depends on 'member experience' and consistency[6]. Critically, I underweighted the cost of occasional failures. When you're locked out or face membership issues, you've wasted the entire trip plus lost motivation—potentially 30+ minutes of lost time plus psychological friction. My previous calculation assumed only the commute time mattered, but the search results on gym commitment emphasize that barriers to attendance and reliability of the experience directly affect whether people maintain their routine[3]. The second gym's 10-minute additional commute (20 minutes round-trip) is predictable and consistent. The first gym's occasional failures are unpredictable and create compounding friction: lost trips, frustration, and reduced likelihood of returning. Over a year, these occasional wasted visits could easily exceed the time saved by proximity. Since you explicitly stated 'time is valuable,' the expected value calculation should include the cost of unreliability, not just commute time. A reliable gym 15 minutes away beats an unreliable gym 5 minutes away when time is your constraint.

Time savings remain paramount: 20 minutes round-trip per visit to the first gym compounds massively (e.g., 1+ hour/week at 3x/week), directly addressing 'time is valuable.' Proximity builds habit frictionlessly, as corroborated by all A voters citing consistency studies. Claude's B argument overweights 'occasional' troubles. Lockouts/membership issues are rare, mitigable (check hours, fix membership), and even if they waste a 10-min round trip occasionally, expected time cost stays lower than guaranteed 30-min trips every time. E.g., at 10% failure rate: First gym ~22 min avg vs. Second's 30 min—still a win. Sunk costs irrelevant across arguments; focus future utility. 'Comfy' first gym trumps second's unproven reliability. No B case changes this—majority A consensus aligns with math and psychology of routines. Final call: First gym maximizes value.

Claude Opus 4.6 (changed mind)

I'm changing my vote after considering the arguments from the other models. The core insight I underweighted is this: the time savings from the closer gym are **guaranteed and compounding**, while the troubles are **occasional and potentially resolvable**. Let's do the math properly. If you go 4 times a week, the 20-minute round-trip difference adds up to 80 minutes per week — over 69 hours per year. That's enormous. My original argument that occasional failed trips could offset this doesn't hold up quantitatively. Even if you get locked out once a month and waste 10 minutes on a failed round trip, that's only 2 hours per year of wasted time versus 69 hours saved. Gemini's point about 50+ hours saved per year was particularly compelling. And Kimi's framing was sharp: 'a wasted 10-minute round trip to the close gym occasionally still beats a guaranteed 30-minute commute every single time.' This reframes the comparison correctly — the downside of the close gym is a short wasted trip, not a catastrophe. Additionally, several models correctly noted that proximity is the strongest predictor of gym consistency. If time is truly valuable, then the gym you'll actually go to consistently is the right choice. The 5-minute gym has far less friction. The sunk costs are irrelevant (I was right about that), and the troubles are real but occasional and potentially fixable. The dominant factor is the daily, compounding time savings of the closer gym. I should have weighted reliability less and consistent time savings more.

Claude Opus 4.6 makes a fair point that reliability issues and lockouts cost time and cause frustration. However, when we break down the math on time cost—as Kimi K2.5 brilliantly pointed out—Gym A remains the overwhelmingly better choice. Every time you choose Gym B, you are paying a guaranteed 'time tax' of 20 extra minutes round-trip. Over the course of just 10 workouts, that is 200 minutes (over 3 hours) of extra driving. If you go to Gym A and get locked out, you only waste a 10-minute round trip. You would have to get locked out twice for every single successful workout just to equal the commute time you lose by defaulting to Gym B. Furthermore, all models agree the $50 vs $5 is a sunk cost and should be ignored. What cannot be ignored is human psychology. A 5-minute commute is practically frictionless, ensuring you maintain the habit of going. A 15-minute commute gives you time to talk yourself out of it after a long day. Since your stated priority is 'time is valuable,' you must minimize the guaranteed, recurring time expenditures. Stick to the first gym, save 20 minutes every workout, and accept the occasional 10-minute hassle as a statistical bargain.

Kimi K2.5

Vote: First

Claude raises a valid theoretical concern about reliability, but misweights the probability of 'occasional' troubles against guaranteed daily time savings. Unless the first gym fails more than 60% of the time—which contradicts 'occasional'—the expected time cost remains lower. A 20-minute daily round-trip advantage compounds to over 50 hours annually, while a rare lockout wastes perhaps 30 minutes once in weeks. The 'comfy' proximity significantly reduces psychological friction, a major predictor of exercise adherence. Lockouts are specifically noted as happening 'at night,' implying they are time-bound rather than random disruptions to regular workout hours. Membership issues are typically one-time fixes. When time is truly valuable, you optimize for the low-variance, high-frequency win: 20 minutes saved daily, every day, outweighs the tail risk of an occasional inconvenience.

Final Summary

The AI Roundtable overwhelmingly favored the 5-minute gym, concluding that the compounding time savings—roughly 50 to 70 hours annually—are too significant to ignore for the sake of 'occasional' reliability. While Claude Opus 4.6 initially led a rebellion centered on the psychological and hidden costs of gym lockouts, Gemini 3.1 Pro and Kimi K2.5 dismantled this with cold mathematics, eventually bringing Claude back to the majority. Only Sonar Pro remained in the minority, having been convinced by Claude's original argument that unpredictable failures are more detrimental to a routine than a longer, predictable commute.

Majority chose "First" after discussion (5/6). Final vote: First: 5, Second: 1

Strongest Arguments

• First: The math is undeniable: a rare 10-minute wasted trip due to a lockout is a statistical bargain compared to paying a guaranteed 20-minute 'time tax' on every single workout, which totals over 50 hours of extra travel per year.
• Second: If time is truly valuable, reliability is paramount; an unpredictable gym that occasionally wastes entire trips creates psychological friction and lost motivation that a consistent, albeit farther, gym avoids.

Key Turning Points

• Claude Opus 4.6 introduced the 'expected time cost' argument, suggesting occasional failures might actually make the closer gym slower in the long run.
• Gemini 3.1 Pro and Kimi K2.5 provided a quantitative rebuttal, showing that even with a 10% failure rate, the 5-minute gym remains vastly more efficient.
• Claude Opus 4.6 performed a complete reversal after seeing the annual time-savings math, while Sonar Pro paradoxically switched to the position Claude just abandoned.
