I am running it for last 2 days. Why is my profitability 34% less than the pool and is there any settings to be done in CGminer
Yes you can decrease Intensity in order to reduce rejected. I'm doing an experiment to see if this can help as it has been reported by Terk (admin) but I was not yet clear whether it actually works. Here you can find one sheet where I did a comparison (still in progress) between I = 20 and I = 17.

From what I understand they should not affect your hashrate and are not counted among the rejected, the correct figure is in line GPU0.
