As well, most of his accounts have no author rewards. I am excluding curation rewards because they can easily be misinterpreted. For instance Haejin collects higher curation rewards than Bernie but his curation rewards that he collects is almost exclusively from his own posts and its really difficult to convey where he will collect those curation rewards from if you don't exactly understand how the blockchain works. But looking at the curation rewards of all of bernies accounts, Idk.

So yes you are correct that the amount made is different than presented... It is however a lot more difficult to convey this information in a way that is easily digestible.
