Not to sure on the answer, to many variables to think of.
lets see....
-first: what your landing on, a flatland will be alot harder on the bike, and a landing on a downward slope or a transition on a jump wouldn't be as hard.
-second: your skill of riding, better skill and you can pump with your body and take part of the drop using your body as a kind of suspension.
-third: the BIGGEST thing is just how *%$#@ed you are in the head and how willing you are to just throw yourself off a huge kicker, gnarly road gap, or best friends porch.

I'm no scientist so I'll leave the math to you WNCbiker....
