power attack is not truly double strength

last few battles I've noticed that my power attack is not being as effective as it should. my combined attack what I mean is double my attack should be about 1.2 mil and in the early stages of battle weekend I had no problem beating people up 2 1,000,000 no problem at all, but the last for battles you have been in when I attack defense leader and I should have beaten him I lose! just right now in our final battle the defense leader have stats of 800 K, 2 battles before this defense leader had 700 K and my power atax are not taking them out. early in the weekend 900 K 1 million no problem but now I can't beat 7? What is going on?

Power attack is 1.5x your attack, not double.

Yup... Ur both right, PA is +50%

50% stat boost

my bad, seems like sometimes it was working better but apparently I was wrong. I guess some people were just close the line and they gave me it, and other times I just couldn't pull through

Even if your PA is the same as their defense, you still have to make sure that their defense is within 80% of your attack PA stat. Anything over 80% has a higher chance of being a loss. Remember to figure out what your 80% of your attack is for more odds of wins and less losses :)
