I was going through old photos and realized it looks like I jumped high in this photo from 4 years ago, but there's no way I jumped as high as it looks. Looks like 2.5 feet by guessing it's a little before the jump's peak, but I can barely get that now with playing sports almost every day, and regular gym + cardio, so getting it back then seems hard to believe. What would a fair estimate be for the vertical?
