I'm planning my long call reserve commute and am trying to anticipate the worst case scenario. So prior to 1759L they can assign me a short call with a minimum of 10 hours notice, meaning 12.5 hours to showtime (assuming they used me the first minute I was on short call).

My question is: if my two commuting options get me there within 12.5 hours, am I still good? Or do I have to actually be in position within 10 hours? Can you accept a short call assignment via CCS?
