Only messing around, ATAG have the same setup vulching is allowed so its more of a personal choice. I think most ppl have had a pop at the easy target when they don't think they have a long time left. I.e. in a 110 over hawkinge with four spit mk2s chasing u, who wouldn't try and have a pop at that spit taking off

but normally I give them a few minutes to gain alt and speed before engaging.
But back on topic, yes they can't promise anything but I am 100% certain the game will be running fine at some point.
