How correct are current mining profitability calculators?

I've been out of the mining game since May.  At that time profit calculations were exaggerated pretty greatly on coinwarz and whatmine.  How are things currently?  What can one expect per 100MH on scrypt, average daily?

Its pretty much accurate for the current difficulty and market price but of course you will have to keep track of the profitability when difficulty and market price changes.

There is some problem with coinwarz. The difficulty update is a little slow. The best thing is to go to Blockchain.info and then copy difficulty and paste it in coinwarz and add details. For easy, you can bookmark Blockchain API. Coinwarz has good UI than others, so I would recommend that site. I hope they will fix it soon or did they fix it?

Mining profitable on bitcoinwisdom is quite accurate. U just need to predict the right difficulty increment trend.

Buying Scrypt asics is not profitable unless you're using the profit from already paid off gear to calculate your ROI.

As an example, the LTC difficulty changes every 3 days so even if the price went up dramatically, everyone would be mining on the LTC network and your nice profits would be long gone in a matter of a couple days when the difficulty goes into oblivion, not like BTC where you have a couple of weeks to reap the benefits during bubbles.

I know there are some people out there that will disagree and say 'oh but you can mine the new coins and hold them until they hit an exchange and pump blah blah'... with all these uber powerful machines coming online right now I doubt that strategy will work anymore when the big asic farms will be waiting to get a piece of that.
