Checked 162 of the 1261 hours with hourly history, 13%. No reading was recorded in 1099 hours. dibs had no hourly record before 25 Aug, which is the other 151 of 1412 plotted.34 of 40 enrolled at the newest reading, 7 hours ago, with 6 left. Seats from 18 Aug 19:40 to 16 Oct 14:42, 26 to 34. 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 7 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 1A shares one room with Lec 1 and every other discussion under it, because that is what a student means by "my class".
