Well I am curious how many others have the exact same issue. If all 20Gh/s of which I'm 20% of are getting this discrepancy then I think it is noteworthy.
I highly doubt that someone has found 0 blocks yet is getting all the rest of our coins.
That makes no sense.
I'm putting down about 1.3GH/s so between you and me, that's a little over 22% I think.
Edit: How long til the next retarget?
Dunno. But I'm going to solo mine and see how things pan out. The rate at which I make blocks on bitparking when compared to rewards is too variant.
Unacceptable especially when I have to pay 5% fee on top of all that variance.
