It's really hard to tell. Honestly, they could change a lot of the mechanics slightly and we'd probably never know for sure, unless GamePress decided to recheck their research. Anecdotally, I dodged a high powered charge move this morning, and it still inflicted more damage than what I thought it would, but with my attacker at 1/2 the CP (I was prestiging), it's hard to tell as my Poke is so much weaker anyway.

Longer defender attack move window?
I feel that after dodging one of those big full attacks like hyperbeam or solarbeam I'm taking more damage then before. I do a dodge and as soon as I see that confirmation, I fire my charge move but the defensive move seems to be inflicting damage more/longer?
