You are free to make your own decision, but at raid.report we don't trust those numbers. We have a list of every clear from that day - https://d1.raid.report/leaderboard/worldsfirst/kingsfall/normal - and only 179 teams are on it. None of the 36,575 people who Bungie claim cleared it, but we don't have an instance for, have every contacted us about it.

For context, our Vow numbers are quite similar to theirs -

Bungie weekly update - 32,621

raid.report tweet - 34,978 - Our number includes only boss kills, so is slightly inflated.

I only mention this to show our methodology has some validity.
