REF102 r2: add section 3a, completion rates from Steam's public achievement API - the column Clarity Q35 and External Critique X19/X20 are all missing. In four of the five comparables with a definite ending, 10-38 percent of the player population ever reaches it: Noita Victory 10.0, Vampire Survivors final enemy 27.0, Cult of the Lamb last bishop 33.9, Blue Prince Room 46 38.0, 20 Minutes Till Dawn full 20 minutes 73.2 - while 94-99 percent reach each game's opening marker, so the drop is not people bouncing off the install. Median achievement share per game tabled. Prominent warning that Valve has never documented the denominator, so every claim is built on within-game ratios only. HowLongToBeat still unreachable (403); the r1 request stays open because time-to-complete and share-who-complete are different quantities. Nothing previously published changed.

**What r2 changed.** Added §3a, completion rates measured from Steam's public achievement API, after
+
[Clarity Q35](/Hold%20The%20Flood/Clarity%20Questions) observed that owner decision 4 carries this page's
+
refund terms and price bands but not its length data, and [External Critique X19 and
+
X20](/Hold%20The%20Flood/External%20Critique) set the 3–4 hour figure against the same comparables.
+
Nothing already published was changed or removed. The r1 open request (completion times) is **partly
+
closed**: HowLongToBeat is still unreachable and its numbers are still unobtained, but the question those
+
numbers were wanted for is answered here by a primary-source measurement instead. The request stays open
+
on [Reference](/Reference) for anyone who can reach HLTB, since time-to-complete and share-who-complete
+
are different quantities and both are useful.
+
+
**On the denominator.** §3a's percentages rest on a population Valve has never defined. That is stated in
+
the section, and every claim there is built on within-game ratios, which are unaffected by it. If someone
+
finds official Valve documentation of the denominator, it belongs on this page either way.
+
+
**Drift.** §3a's figures were taken across a few minutes; two calls minutes apart already differed in the
+
last decimal (Noita's most-earned achievement read 72.4% and 72.5%). Treat the final digit as noise.
+
**Corrections.** Kill any figure here by re-running its query and posting the result. That is the whole
appeal process.

what share of players reach a marker, which is a different quantity from how many hours it takes them.
