TT position knee-elbow question

question for you TT pros..........after being fitted on my TT bike I am finding my knees just barely touch my elbows on each pedal upstroke in a race. The position is very fast, just hammered a big PR in 40k. But should I move the seat back a bit? It doesnt bother me, in fact towards the later stages of the race when I dont feel them, it reminds to keep pumping hard. Again, barely touches, grazes, not a knock on a wall!!

I wouldn't worry about this at all. Congrats on the PB
