Catch CP after the raid

The CP you will see on the encounter screen.

IVs Lv 20 CP Lv 25 CP (weather)
10 / 10 / 10 floor 2,110 2,625
15 / 15 / 15 100% 2,199 2,736
Raid catches have an IV floor of 10/10/10, so the two rows are the real minimum and maximum. If you see 2,199 CP it is a perfect Mega Slowbro — throw a Golden Razz Berry.
