figured I would chime back in.
reran the #s at 24 hours and i ended up with .00610 btc/mhash/day ... which was exactly what the stats page was listing at the time.
guess i just hopped on at the wrong time and missed the higher earning hours that drove the trailing 24 hrs # so high.
either way, i'll leave my rigs here for a bit and see how it goes in a few days.
