Seats over time

Nothing read since 16 Oct, 2 hours ago. Over about 2 months before that, same seat count, but the seat count moved and came back.

5 of 15 · 10 left
17 Aug 16:4216 Sep 16:1716 Oct 15:52 · 2 hours ago
Checked 168 of the 572 hours with hourly history, 29%. No reading was recorded in 404 hours. dibs had no hourly record before 22 Sep, which is the other 868 of 1440 plotted.5 of 15 enrolled at the newest reading, 2 hours ago, with 10 left. Seats from 17 Aug 16:42 to 16 Oct 15:52, 5 to 5. Checks are not continuous monitoring. Changes between checks may be missed.

A dot is a reading where something moved: the seat count, the status, or the waitlist. Flat between dots joins recorded counts; changes between reads may be missed. The line starts when dibs first saw this section rather than reaching back before it existed. The last one is the last time dibs read this section, moved or not, and that was 2 hours ago. It is where the line stops, not where the count is now.

How readings and alerts work

Dated seat counts can be available even when hourly check history is missing. Gaps do not show whether seats changed between observations.

Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.

The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.

Class chat

Nobody on dibs watches this class or has it on a plan yet. Nobody has posted yet.

Dis 1B shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".
