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.
Is your question does Awesome Miner use nethash or does this plugin use nethash?
Awesome miner uses the profitability which the pools provide.
I believe this plugin uses the nethash to calculate rewards and then uses exchange rates to calculate profitability.
Yep, I took a closer look. The plugin is using average nethash to calculate profit and send BTC per MH value to Awesome miner. Awesome miner is using WTM and they use average difficulty to calculate profit. So right now i dont think that plugin calculation is accurate, at leaast from my test when i was using average nethash to calclulate my profit the value was always way too higher. Then I found this
https://bitcointalk.org/index.php?topic=567730.msg28352235#msg28352235 and on the next post was this "Nethash is only an estimate, this value is never real and yes the real mining formula uses difficulty - thats the value relevant to finding a new block." which explained why my estimate was always high when using proportion of nethash average and my hashrate to calculate the estimate. Then I started to use the average diff and realised WTM is using it too and its way more accurate.
