FYI, I just sent this ticket. I'll post any responses.
"Has there been a change to the practice engine to cause the sudden increase to the rate of ratings loss for skills practiced 0 minutes? I noticed it beginning with this afternoon's practice in Phelan. For example, please see my Oregon team in Phelan. Woods went from 9 BH to 5 BH in one game, Horner went from 40 LP to 30 LP, Ferreira went from 33 BH to 31 BH. There are a few other examples. If possible, please let me know asap, as if this is true, I need to change my practice minutes before the next practice. Thanks very much."
