NOTES:
- Using a second X Attack on Chuck increases your happiness by 1
- The numbers in the table are OHKO% chances
- The numbers for "TOTAL" are average number of turns saved, assuming the following:
	> You hit no spinners
	> You use Return whenever you can (not optimal on Houndoom/Rapidash/Exeggutor on lower DVs)
	> Slowbro does not use Curse
