Trophies earned percent calculation error?

[x5312]

I have 47 of the potential 59 trophies in the game = 79.66% yet my profile says I have 76% trophies earned. Why the error? Am I missing something here?

if bronze is 1
silver counts as 2 bronze
gold counts as 3 silver or 6 bronze
platinum counts as 2 gold or 6 silver or 12 bronze

Ok, I think I get it. Thanks!
