In all honesty, he has Jamaican bloodlines and based upon what I’ve seen since I’ve had him I’d wager that he has the ACTN3 gene.
When he first arrived in 07 2-3 timers got him at mid/low 4.5 (hand). Now, regardless who’s watch you look at he’s 4.2 high/4.3 low
I busted one of the gates on my laser which is why I’m going with hand times for now.
