So now you take the Method K frames while having a Synch listed as careful. For Encounter slots what you do is you take the current frame (the desired frame) add 1 to that frame. Take the last 4 digits of that PID convert it do decimal divide by 656. If there is a remainder meaning a decimal like 12.72436490321647213 just get rid of everything after 12.
Once you finished dividing you take that number and put it into this chart:
Slot 1: 0 - 19
Slot 2: 20 - 39
Slot 3: 40 - 49
Slot 4: 50 - 59
Slot 5: 60 - 69
Slot 6: 70 - 79
Slot 7: 80 - 84
Slot 8: 85 - 89
Slot 9: 90 - 94
Slot 10: 95 - 99
Once you find the slot, go to Serebii's BCC page, very left is slot 1, very right is slot 10.
