I might be totally wrong (sorry if it's the case) but I think it's really 3 times the amount (3倍 = 3 Bai).
They say that for a Moe to defeat the best Sexy it need to have 4,439 SED.
Bade need 3,775 SED to defeat the best Moe.
And Sexy need to have 4,105 SED to defeat the best Bade.
All those value are for the Japanese version.
