data as of 2026-10-24 12:44 (today) · today is still filling · last refresh interrupted

Outcomes every instant request from an Indian student, by IST day · losses stacked as % of requests, fulfilled as the line

By hour of day over the whole range · where in the day supply runs out

Volume requests, and what they billed

Where each day's loss fell each quarter's share of that day's lost requests · counts on hover

By grade requests as bars, the loss rate as the line — a grade asks more because more students are in it

By subject the busiest 10 · loss rate on hover, because a long tail of small subjects has no rate worth reading

Was anybody offered it? of the requests that were lost, how many tutors each was pushed to

30.4% nobody was pushed 4,303 52.3% pushed to 1-2 7,407 11.5% pushed to 3-4 1,633 5.8% pushed to 5 or more 822

A lost request with no rows in the push log counts as “nobody was pushed”, because that is what it is. This separates a routing failure from a supply shortage: both leave the student without a tutor, and only one of them is fixed by recruiting.

…and at which hours lost requests as bars, the share nobody was pushed for as the line

How deep the offers went, by hour share of that hour’s lost requests · counts on hover

The line above is only the red band below. Splitting the rest apart separates a matcher that never started from one that gave up after two tutors — the same loss to the student, a different repair.

Could the idle tutors have taken it? under 100% is a shortage of tutors; well over is a routing problem · the tutors behind it →

fixed week 2026-10-16 → 2026-10-23 — not 2026-10-08 → 2026-10-21, unlike everything else on this page. Tutor presence is written once a night, so it is always a day behind and cannot be re-cut by date.

Capacity is idle tutor-hours × sessions per busy tutor-hour, not a count of idle tutors: the average idle tutor is online about 22 minutes of an hour, so counting heads overstates it roughly threefold. It is an upper bound on what better routing could recover — it assumes idle tutors would work at the same rate as busy ones, when some are idle precisely because they decline. An hour that still comes out under 100% on that generous assumption is genuinely short of tutors. Hours that lost nothing show “—” rather than 0%.
