1. My rejection Rate is very High bRejected: 83.9 kH/s (13.8%)
2. I am running Sapphire R9 280X. The cgminer show avg 728 KH/s where as on the website 631.7 kH/s 24-hour Average.
3. As per the website the BTC per day is 0.01218 BTC/day per MH/s.Based on this calculation the BTC/day for 700 KH/s must be .008526. However i have only 0.00565835 BTC. i e 34% less than pool profitability.
Please advise
Raw hashrate is 728 kh/s. Rejects are 13.8%. 728 kh/s * (1 - 0.138) = 628 kh/s effective. Pretty much exactly what you're seeing.
And I got the same BTC/MH yesterday. Seemed to be a lower-than-average profitability day.

To everyone struggling with very high rejects: You can tweak cgminer to use a lower intensity while still maintaining a high hashrate via the -g 2 parameter. But that will only help if your rejects are actually
higher than the pool average. If it's already equal or lower than average, then you don't really need to worry about it because the reject rate is already factored in the profitability calculation, according to Terk.
