Did you account for the change in Global Diff?
You can't test two pools at two different times.
Both pools are PPLNS, 24 hrs is way to short a time for the pools. Global Diff has been changing. And your 45 Mh/s is on the low end.
I've been getting over 150% of estimate on Virtopia since the new pool went live. I've mined a lot at Suprnova, and it's a fine site, but your only going to earn the estimated amount for your hash.
You can see my results on any block explorer RRD5w8tdDGyCPFxXVBBYWoC8GghqS6Kk5T
Well today isn't very good day on virtopia. Only 6 blocks found so far.
