Good question. If I recall, with TR you're supposed to wait a few days between reductions for depot to adjust. But, acro+SRT overrules those rules lol
I'm not getting the feeling of "yes this is for sure SRT related" , more like "ehhhhh is it or isn't it?". So, I'd lean towards keeping the 50 because these numbers are great for him right now. But if you really really have to fight to keep him afloat, then I'd probably reduce.
