... Or some chests are fake and they just act like chests so that we can't actually run the maths accurately.

Lwmark had something really interesting yesterday: we traded and we was showing be a purple forgotten blade, can't remember the level of it. It had some nice stats and Lwmark insisted: LOOK at the blade!!! I didn't get it at first but when I clicked on the 'view on avatar' tick box: IT WAS A STAFF. So I reckon that if staves can hide as blades, tables can hide as chests.

Maybe we destroyed 1mil chests and 5mil tables. Ultimately, STS is always right (to answer the original question!) :-)
