This goal has the following fine print specified by alephnull:
This is intended as a time-limited goal to clear my "Alpha" deck backlog (the cards that are more effortful to study, so I typically can't do them unless I'm at my desk).
If I have completely cleared my backlog on a beemergency day, I'm allowed to enter whatever number clears the beemergency. (I've tried to set the goal total so that this doesn't happen, but I might be slightly off near the end.)
