What students say

dibs measures outcomes: grades, seats, how fast it fills. For what the class is actually like to sit in, BruinWalk has the reviews.

There are no BruinWalk reviews of this course on record as of about 1 month ago, so nobody has told dibs what kind of work it sets. That is dibs holding no reviews at all, and not reviewers who wrote without mentioning the work.

dibs read 168 of the 536 hours its hourly record covers, 31%, and did not look in 368. dibs had no hourly record before 9 Sep, which is the other 548 of 1084 plotted.19 of 45 enrolled at the newest reading, 2 hours ago, with 26 left in its discussions. Seats from 17 Aug 12:32 to 1 Oct 15:03, 13 to 19. dibs read 168 of the 536 hours its hourly record here covers, 31%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 368 hours dibs was keeping a record and did not reach this section. Nothing before 9 September at 08:00, where this section's record starts, has a read either way, which is 548 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.

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

A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.

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.
