Gambit isn't really about activity though, because it's about spamming tons of stamina rather than focus. That also means that you do indeed benefit massively from having more stamina, since the more stamina you get from one consumable the higher the odds are you get another shake/peronamin with the stamina you just got back. Also, I know from your past posts that you're not a big fan of camping caches, which is pretty important during the gambit to get more consumables. If you want to get ahead in the gambit through activity, camping caches is pretty much the way to go.

I'm also not sure why you wouldn't use peronamins during the gambit. When else are you going to use them? Only Gambit really requires you to use peronamins and imo you shouldn't use consumables outside of events.
