Dodge Windows irrelevant?

You are right. I do see outdated defensive sets supported by irrelevant long dodge windows.

I don't believe movesets were ever ranked with their dodge window in mind. I believe they make an assumption about the level/stats of an attacker/defender, and then they model out a fight where they duel to the 'death' and nobody dodges anything. Then they rank out which moves deal out the most DPS and rank them accordingly.

It's up to you to then take that DPS information, and apply your own judgment to which combo you want.

For example, Headbutt/Hyper Beam is listed as the best defensive setup for Snorlax but most everyone would agree that Headbutt/Body Slam is more difficult to match up against. Why? B/c most people dodge at least the charge attacks and it's much easier to dodge 2-3 Hyper Beams than 6-7 Body Slams. Not just b/c there's more of them, but also b/c the ability for the defender to use the move back-to-back takes away your ability to safely use your charge attack after the defender uses theirs
