This year it ranges, the cpu can get gold, silver and bronze for training. From what I have seen more bronze but some silvers and even a few golds.
Firstly I tried just simming to get bronze each week but found most of my players didn’t progress through a season.
I have changed now to playing each training once and sticking with whatever medal I get for the rest of the season. I also use the suggested training each week rather than selecting those I have won silver or gold on every week. I play cpu vs cpu so to be fair most of them are bronze anyway as I’m not so good playing myself lol
