Bro I understand that you love AP Exp but you are unnecessarily taking it a bit too seriously. UPSK too runs at 130 MPS with 2 stops and can easily run ahead of AP Exp if required, there is no issue of it not getting OTed if AP is on time. There isn't going to be much difference if AP does not OT a few trains if schedule can be maintained, there is nothing like poor controlling in this case, plus you want Rajdhani like priority for AP Exp which is impossible for an ordinary SF train.
