Problem with submitted shares not matching what i paid for.

I verified the orders i submitted yesterday and today for the amount of shares actually submitted to the pool and they are at least 20% off. Which means i am paying 20% more for the hashrate i hired.

Has anyone else had similar problems?

Here follows my calculations:

OrderPrice BTC/TH/DayTotal BTCUnspent BTCLimited TH/sExpected Shares   Actual Shares (on pool)

#2521580.01030.2057020100401749338.9

Has anyone any idea what happened? Can i get my missing shares refunded?
Thanks,

i would suggest to use only one fixed diff on the pool
( can be really high, statisticially this does not matter )
i also had problems with vardiff .. this is why:
nicehash sometimes sends "old" shares ( from slow miners ) when diff changed, but block did not change. this leads to two problems:

a) when diff is doubling:
50% chance to be below new diff = get rejected
50% chance to be above new diff = get a share with 200% diff
so this case should be no problem on average

b) when diff is halving from 2048 to 1024:
100% to be above new diff = gets always accepted
but: nicehash thinks the share is worth 2048 , whereas the pool thinks it's worth 1024
so you will pay more than you get.

so i expect a often changing diff to cause problems!
i set diff to like 65536 ..only few shares are submitted, but each has a high value..
so i reduce network load, reduce pool load and avoid those problems!
