Even when it's up I'm not getting credited for my submitted work...

I got no credit for block 4850?
My miner was chugging away at ~360 Mh/s for the entire duration.
Does it have something to do with the recent difficulty jump?

And... fixed.

I just started last night, and I'm running the latest poclbm with my 6970 and pointing to mining.bitcoin.cz (~360 Mh/s at default clocks, -v -w 128).

The only question I have is, why does my "confirmed reward" amount not match the sum of my confirmed rewards listed on the stats page?

My Reward	Block Number
0.02978366	126607
0.0300458	126603
0.04531619	126601
0.04239298	126599
0.031207	126597
0.04041885	126596
0.04498766	126588
0.03822266	126574
0.04406936	126562
0.03143972	126551
0.03743996	126549
0.04310043	126544
0.03367803	126535
0.00921723	126531
0.0211114	126530
0.01621386	126517

Adding up those rewards yields 0.53864479.
But I've only got a confirmed reward of 0.31948031.

All of the rewards/blocks used in that sum have been confirmed.

Is there something I'm missing?
It's as if the latest 6 blocks aren't being counted, even though they're listed as confirmed.  Is there an additional delay between showing up as "confirmed" on the stats page and showing up as part of my confirmed reward?
