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.

Forgive me but where is the pool average for rejects? I am at 24% rejects which can't be right! When you use the g2 parameter are there any general rules of thumb? For instance do you usually start with half the -I and -g2?
Thanks in advance.

Average rejects are displayed alongside your own rejects in the graph on your user stats page. Right now it's about 25%, so yours isn't even particularly bad.
All you need to know about -g 2 and intensity tweaking is written here: http://www.overclock.net/t/1461916/tutorial-ultimate-guide-to-tweaking-amd-cgminer-3-7-2-kalroth-edition-sgminer-instructions-included-aswell-get-the-most-hash-out-of-your-gpu

So are you trying to say that the same settings we all use and have used for months/years on profit/coin switching pools don't apply to yours because you all are doing something beyond what the most venerable pools are doing in this space? I'm just trying to understand why the admins of the pool are doing this finger pointing the miners' way. I've never seen reject rates above 10% ever... but here it's like I'm giving away 25% of my hash power and not getting the results I expect from a 90% or better share efficiency.

I want to drink the koolaid guys, don't get me wrong. There's a LOT to like here; that said, pointing the finger at the miners and saying they are doing something wrong to experience this problem only with your pool sounds unreasonable.

That said, I will adjust my mining configs tonight a bit and see if it has any appreciate effect, but I would like to know, in a detailed technical explanation from the pool admin(s) why this is our issue and not a pool-side issue.

Thanks a bunch for the work...

I'm doing a log with the measurements of my gpu to find the best configuration for now lower the intensity as suggested several times by Terk really seems to work, please look here: https://docs.google.com/spreadsheets/d/1B-_UkIrGZYray8jb4K3Jnwx3JgweBHdaTCxgccgtFio/edit?usp=sharing
+1 for your question.
