Friend your estimations are extremely misleading, Pixelcoin is the top coin in your list now but it is very fake info, probably other coins are false.
+1, I have to agree with gzabi. Here's another example, your site shows EFL with a diff of 3.96 at the time of this posting but the actual diff at this moment is 11.175 -- more than twice as much. Where do you pull your diff information from if not from the wallet daemon? Needless to say, your site isn't useful if the information presented isn't uptodate, and I'm inclined to believe that there are likely other inaccuracies besides those 2 coins.
Edit: The diff for vertcoin is also wrong: your site shows a diff of 238.66 but the real diff is 245.6. I was hoping your site could provide some useful gauge of which coins profitable but until this issue is sorted out the information presented is highly misleading.
I seriously doubt the site is running daemons for each coin, it's probably scraping the numbers from some other site(s). I'd like to be proven wrong however.
