+One limitation is that the algorithm assumes that any day you worked
+on is a day on which you should have worked the full number of
+hours. So if I log a session that goes from Friday afternoon to after
+midnight (that is, early Saturday morning), it assumes I should have
+worked 16 hours those days, whereas in fact only Friday was a
+workday. I solve this by editing my hour reports manually whenever
+this happens.
