I don't know if my alarm didn't go off, or if I just slept right through it, but +7.5 is the last check I got until PMPS and I have no idea how low he went after that.

The more sleep I lose, the more likely I am to sleep through an alarm, so it becomes something of a catch-22 in this situation... If I go to sleep when sleep-deprived, there's a chance I'll miss the alarm, but if I stay up to monitor, then I'll be even more likely to sleep through the next one when I finally get a chance to sleep. Fortunately, this is the last night of overnight work until next week. PMPS was 98 and we're back down to 12.25 units.
