Thanks a lot Doug! Been waiting for this for what feels like years.
I believe the cut-off point is 3.4%. Using that, and assuming no major shifts in April, let's see...
Heracross: Will stay OU (thankfully, we don't need that in UU)
Umbreon: Could go either way. Very slightly above the cutoff in March, but quite a bit below it in February. Time will tell.
Miltank: Will move up to UU.
Hitmonlee: Will stay UU.
Electrode: Will move up to UU.
Jumpluff: Will move up to UU (haven't seen this one at all; to be honest this surprises me quite a bit)
Nidoking: May fall to NU. Tough case to call.
Nidoqueen: NU. Not even close.
Drifblim: Again, NU easily.
