Why are you multiplying by three quarters instead of one half? Not that it matters, as 90 is still more than 80. (And besides that, ExtremeSpeed is already an 80 BP neutral move for Tentracruel, so Crunch wouldn't matter there even if CC were weaker.)edit: IIRC Jimboon I think Tentacruel is hit harder by Close Combat than by Crunch. 120*1.5=180 180*.75 = 135 base power while Crunch is just 80 Base power
