I've never seen a week where a Proficient > Proficient GS player did not drop. In any case this is easy to check: starting next week (now it's too early, not many players have high enough GS) we can check players with 10 ST and 9 GS that are for sale before and after the training update.
Note that 10 out of 26 players on the TL with 10 ST did not pop in ST last week, so they went through at least 1 training update already without dropping.
