So basically a 48 flat from a dive 12 years ago, probably not much chance from a push. Why not do a dive by the way?

You were a good college swimmer, but seems you were more a distance guy. And I think 24.5 is not going to be enough going out either, you will need a sub 24 at the very least. But hey, good on you for setting a super hard goal, stretches out your abilities to the limit
