All below average Zapdos catches
Answers
Some statistics from my own raiding.
caught 8/15 articuno, two in the 90's
caught 9/15 moltres, one in the 90's (failed to catch it.)
caught 4/6 zapdos, one in the 90's.
That's 4/36 legendary bosses in the 90's. To conclude there is nothing remarkable at all about you having seven zapdos' that aren't amazing.
Come back when you've caught 20 like that, then we'll talk ;)
Hope I never wind up disappointed with 90+ legendaries. I was PUMPED to get my 1st [email protected], didn't care where the 14iv was... Started powering up immediately (which I wouldn't regret if I got a perfect 1). My best ho-oh, out of 4 total, is 88.9. I'm not gona have any regrets about spending some of my few/precious, 65 or so, rare candies if its still my best by the time they're gone.
My moltres' down in the low/mid 80s is where I start getting hesitant/disappointed. Other than that, mon recommended by PoGo in the lounge, or calcy battle simulator - above 2000cp&88% usually get the dust b4 others.
