Corrections
A wrong number on a reference site is worth fixing fast. Here is how.
Check the stamp first
Every page carries a build stamp: the patch it was read from and the date it was read. If the game has patched since that date, the page is waiting on its next pull, and the value you are looking at is the last build's, not the current one. That is the most common "wrong number", and it fixes itself when the next build lands.
What a correction can fix
Because every value is generated from the game files, a genuine error is almost always one of two things: a decode that read a column wrong, or a join that paired the wrong rows. Both are fixable at the source and, once fixed, correct every page that shares the fault. A value that simply differs from another fan site is not necessarily wrong: Variety Gamers shows what the current client contains, and other sites are often a patch or two behind.
How to report one
Reach out through the About page. The most useful report names the entity, the field, the value shown, and the value you expected, so it can be traced back to the exact table and row. Corrections are applied at the source and the page's checked date is bumped when the next build is read.
