Oh yeah, that's just because of the weird way Plea works where there's no real medium-hps amount. You either have a low number of Atonements or a lot, and there's no way to sit at 8 or 9 without using PWR, but once you use 1 PWR you might as well go all the way because it's more efficient at that point. I personally don't like the ramping Plea cost mechanism because it forces that dynamic, but it is something we have to work around.
