Wrong Pidgeot Attack grade?

There may be 2 reasons:

You can still dodge most moves with Hurricane, the yellow flash lasts for 0.7 seconds and the quickest move is about 0.4 seconds. 1.5+0.7=2.2, if the defender's quick move's cooldown is longer than 0.5 seconds, the quick move can be dodged.

DPE and/or Weave damage are more accurate than DPS, and DPS is for counting the cycle damage in a short period.

DPS of charge moves is not very meaningful, since it doesn't account for the time needed to charge it up. BB does 90 base, H does 110 base, and both take the same time to charge up. BB itself being slighly faster doesn't change that.

Brave bird's DPS has very little to do with how good/bad it is when attacking, the real issue is, BB has 90 power for 100 energy, where Hurricane has 110 power for the same ammount of energy, and the difference in cooldown is not so big that it overshadows the DPE (Damage per Energy)difference.

If i use my charged moves metrics - time corrected DPE
tcDPE = (Damage - 10 * time) / (Energy + 10 * time),

Hurrican gives 0,65
Brave Bird gives 0,58

So Hurrican is indeed the better charged move, but not by far.
