That is the time the aft prong strikes before the front prong.

If you stay in one IFR, the two statements above are contradictory. If
they strike simultaneously, how can the rear prong strike before the
front prong? You are jumping IFRs again. Sure, they strike
simultaneously according to B, but not according to A, and it is the
view according to A that we are interested in, not the view from B. As
measured in IFR A, the prongs on B are 0.866m apart, and do not strike
simultaneously.

Apart from answers to the questions at the end, I expect you to
find and show a little typo I made in my other reply.
