Code:
Speed Days Moved
10 2 5 8 11 14 17 20 23 26 29
18 2 3 4 5 6 7 8 9 10 11 13 16 18 20 23 25 27 29
Getting out of the corner safely should not be a problem.
Edit: Hmm, examining the chart, it appears that emergency propulsion works in a very non-intuitive way. Rather than simply calculating movement days as normal with the total movement available instead of the base, the normal movement schedule for the base speed is simply modified by cramming all the extra moves in as early as possible after the first normal speed move.
