Bigger people hitting slower

Hello,

So I've seen a lot of "it's an advantage to be smaller as smaller people are faster and the game tracks velocity instead of power".

This makes sense, but I was wondering if any bigger people are finding their velocity is actually lower than smaller people? My reasoning is: if you are bigger, you have longer levers (limbs) and so your fist can accelerate for longer, and therefore be going faster by the time it hits.

I realise I'm also conflating taller with bigger, but I think these posts often do.

So, what are you're thoughts/findings?

I'm thinking 6ft and over = taller
