TP and I, have been mass debating over this

I think that the DD bikes should be able to pull standard or taller gearing at CC, but TP thinks he needs to go shorter.
Thing is, TP was pulling 9,500 revs at Cadwell on the same gearing as he had at CC and couldn't pull more than 8,000 revs, yet the straight at CC is easily twice as long as at Cadwell... how strange is that?!?!?!
Everyone seems to be running shorter gearing than stock road settings... I just don't get it
