wow! i only got 2 Shinies! i dunno, i kinda felt like there were less Charmanders and Shinies this community day. at least in the park we were in. i usually catch 4 or 5. just asking random peeps, the most Shinies found was only like 4.
the two Shinies i caught don't have good IV's but hey, don't they look great?! i got a 98% Charmander tho. i only knew that b/c a guy in the group ahead of us shouted very loudly several times to everyone - "Hey there's a 98% Charmander at this stop!!":
also i got my first Ho-Oh in a legendary raid. i really want a Shiny Ho-Oh w/ rainbow wings.

we beat a Latias in another raid, but i failed to catch it.

i already have 1 tho.
awww mah bad! forgot to bamp. i only missed 1 community day i think - the Pikachu one in January b/c i was sick. i still got lucky and caught a 0.1 Shiny Pikachu around the house lol.
FYI Alola forms/morphs are coming soon! i can't wait to catch/evolve a tall goofy Exeggutor.
there's a way to manually calculate it. it's based on a scale of 0-15 for attack, defense and stamina. so u give your Pokemon a max of 15 points for each of those things during it's appraisal, add it up and divide by 45. or just use an app or online calculator like this:

but personally i don't use IV's to judge my monstars - i just use the basic appraisal of Amazing, Strong, Decent and Not Great (Team Valor's assessment). i keep Amazing and Strong and lesser ones if they are kool, unique, Shinies or i caught them in a city i visited while traveling.
