Do field research encounters always have worse stats each subsequent time you do the task?
I ask this regarding field research tasks done more than once- this could be totally baseless, but of the multiple spinda, jynx, entei, etc. that I've gotten, the one with the best stats has always been from the first completion and they get a little bit lower each time. Is this an established fact I missed the memo on? It's no big deal but I'm a bit curious.
Same answer as to why some people seem to get more shinies than others: random is random is random. From research, you have a 1/216 chance of getting any specific IV spread. Given that so many more IV spreads are less than ideal it's easy to forget you're more likely to be given a bad hand than a good one.
