Are you sure Awesome miner is using nethash average to calculate profit? I havnt used it much and havnt check but i have an app which basically do the same thing to show mi the profit of coins which are not listed on WTM, first i was trying to use the average nethash for 24h and the value was totally unusable. Then I changed to collect the difficulty and use a formula to calculate the profit and this was way more accurate and gave me the same estimates as WTM.
