FC POOL - GEEK Earning Question

[nwilloughby]

Ive been mining with Geek Pool for a few days and the earning report looks like this:

However i've only seen 0.63FC in my account, is this due to the the report not taking into account the PPLNS scheme? also currently my account balance is 0.9 FC but i can guarantee the next transfer wont be anywhere near that.

Thanks
