No way are those figures correct. The O2 is never over 30,000 capacity. According to what I’ve just googled both Earl’s Court and the O2 are a maximum 20,000 but that can be stretched I imagine. Just found this article from 2007 where metallica apparantly broke the attendance record with just over 22,000.

Those figures are correct as they come from the official boxscore figures. The capacity at Earls Court for the Maiden shows in 2006 was 16,341 per show, with the first one being sold out and the second one not. The capacity at each O2 show in 2017 was over 17,200.
The Metallica record is a result of them playing a small stage in the middle of the general admission area.
