You're good Mr Weston (not hi-jacking at all). This is all information I am hoping to discuss.

My understanding from reading other threads on timing is most folks will continue to add timing until they get high knock counts and retard, then back the cell(s) down just a tad. There is a finite point where there is too much timing. We want the max timing possible but as soon as we hit knock, we are losing efficiency (obviously there is knock from other conditions besides timing but for this conversation we are speaking purely of timing).
