Please keep in mind the coin employs 'Kimoto gravity well' difficulty adjustment retargeting on every single block (!) This, and small/irregular cpm, makes all calculations based on averaging pretty much inaccurate, and this includes calculator, (some of the) charts and hashrate displayed on sites. If you PM me the MMC address you mine with, I could provide you the exact calculation towards your payment for one of last blocks found on 1gh.
