As was previously reported with Superior Defender's Bastion: Recharge/Chance for Minor PBAoE Heal, the VEAT ATO Superior Dominion of Arachnos: Recharge/Chance for -Dmg and Terrorize is also using the non-catalyzed Recharge boost of 18.5% instead of 23.1875%.
FWIW, I found these two issues using the raw data from Uberguy's incredible City Of Data site, so I'm confident that only these two sets are affected by this bug, i.e. the only two boosts having superior_scales=false with only_at_50=true.
