You’re already plenty fast! I’ll try to explain escaped in one image using DWPS/UX. Troy has extensive ideas about how to actually make it happen in terms of movements.
The guitar has wood 110 and six strings, from high E 100 to low E 105. There is a pick 115 that has a tip 120. Position 115 is “escaped,” because the pick is free to choose any target string that it wants. Lets’s say the pick 115 decides to hit D: it will end up in position 130 possibly resting against G (a rest stroke). So this trapped pick is somewhat limited: It can go backwards through D again to return to 115, or it can sweep forward through G and possibly rest on B. Note that it cannot sweep through D towards A, because it’s ratcheted in the wrong way to make that possible. This is the absolute simplest description of downward pick slanting + upward escape that I can think of, I hope that it helps.
