This is NOT a great strategy, although better than waiting for the 100-1000ms collection you're still at the mercy of the GC which can be very random and you will miss some VSync for sure doing that even if you're supposed to have some "room". Missing a VSync in mobile means that the refresh rate will switch to 30hz for a brief moment, there is no in-between (ie; 54 FPS or something like that) which is pretty noticeable. The only "great strategy" is to have zero alloc (or close) while gameplay is running and if you want to go the extra miles, disable GC completely and call it only in some appropriate moment (level loading, bringing up the menu, etc.).
