You have all those individual numbers, awesome! Yes, that's a good idea to loot Silver focus chests and Gold EOS chests. And from today I can add, that it was easier today already then yesterday to add loot in Gold III and being back in Gold II again. Someone may compare RP in my battle list. It's not a long list, becouse I am not battling a lot. Yet I easily added two more chests each, EOS and focus with only 4 battles (all won). And it might even be a different on different times of the day.
So from this I definitely consider staying in Silver I longer then I did this time.
