Added missing items. Thanks!

When I did peronamin + 2 half pero puddings it was 50 minutes and not 60 minutes (though it should add up to >=780). The reward was silver last I tried.
Also, all of the silvers I got were the smooth silver reward, rather than the rougher one. Not sure if relevant.

Edited this post since I mistakenly said peronamin + pero pudding at first, which is 60 minutes.

It seems as though the reward capsule itself is determined by the wait time. Looks like it goes skinny bronze -> fat bronze -> skinny silver -> fat silver -> skinny gold -> fat gold

My guess is each container holds more rewards than the previous tier. May or may not necessarily be better rewards, just more of each one. But I guess this is what the testing is all about.
