Ultra slow payout @ Burnsides LTC pool?

[alz]

Hi Guys,
I have been mining over at burnsides http://ltc.kattare.com.
after 36hr mining my balance is showing Balance: Ł1.988

This is way lower that the 2.5ltc a day i was expecting for 2400 kH/s at the current diff.

Is this normal?
my stale rate is 0.9 and the 24hr hashrate graph show ive been consistantly over 2400 the whole time.

thanks for any help or advice anyone can offer.

The server can be down sometimes, hashrate is not constant, you will never do the maximal expected value.

Thanks for the reply.

The server has not gone offline in the last 2 days and all the graphs both on the pool end and the one derived from cgminer on my rig show an unbroken constant hashrate of over 2400kH/s
as I said before the estimate is for 2.5ltc per day so I should be seeing 3.75ltc ish for my 36hrs mining.
Is the "estimate" really likely to be %40 off?
or is there another reason for the discrepancy?
I really dont think it is pool downtime or inconsistent hashrate but thanks for the suggestions.
