I started each test for LoL at 100%. It would have been better to play continuously for 30 or 1 hour, but note I cannot control the game length, but like the idea of a uniform cutoff. Also I was more interested in temperature than battery. The mistake of not closing out all other tabs for the non-gaming usage makes the data points less useful, I agree. Atop that, it is likely there were more background processes running on the Max that I did not control for. I did intend on measuring the temperature with and without the cooling to cover my workflows, to each their own. Sure the comment on the keyboard was a bit non-sequitur, point taken, I am trying to take the entire experience into account. I didn't collect FPS because it is constant for both laptops (~70-90 fps), this is a cpu-intensive not gpu-intensive game, for instance ~50 threads running 100% on one core.
If you do want conclusions, the Max does get hotter but only noticeably on the top vs. the bottom (bottom matters more for "lap" use), and it evens out over time, while the Pro maintains and sneaks up over time. Honestly if I was executing other non-game cpu intensive tasks over sustained periods, if I'm using it on my lap, I'd use the cooling pad for that as well. At light usage they are the same temp and battery usage. In the second round of non-game tests, for the 30 min duration, battery usage was even after i killed the extra tabs and background processes. At this time don't plan on repeating any of this, and I do appreciate the feedback on the attempted experiments. Thanks.
