I'll keep this short:
I've had five critical captures total.
One was a week ago, VS a Cinncino, but it failed.
The second was earlier today, and was successful.
The third, fourth and five were all in the last five minutes and were all successful.
EDIT: Sixth and Seventh. if it counts for anything, the last five were outside Dragonsprial Tower...
Am I just lucky... or is there some manipulation I unknowingly triggered?
EDIT: Streak broke, and began again after two captures.... and stopped again. Caught a Drilbur in a totally different area, so its not location, and I've changed the seasons a few times, so it's not date based either.
guess a capture log makes sense:
1 - CRITICAL Cinncino : FAILURE
2 - CRITICAL ?
*other stuff, may or may not have captured pokemon in this span*
3 - CRITICAL Deerling
4 - CRITICAL Sawsbuck
5 - CRITICAL Mienfu
6 - CRITICAL Deerling
7 - CRITICAL Vannillish
8 - NOT CRITICAL Deerling
9 - NOT CRITICAL Deerling
10 - CRITICAL Drilbur
11 - NOT CRITICAL Tympole
12 - CRITICAL Cottonee
12 - NOT CRITICAL Sewaddle
