Yeah I am a bit puzzled what to do with chacha.
I am a miner owning currently 280x and 290, so everytime new n-factor kicks in, I check the default hashrates and extrapolate the coefficients. I think it is impossible to predict it for factors that did not happen yet.

Edit: If you have any suggestions, feel free to post here or contact me through form on site. Email can be left blank.

Plus, two identical cards, differing only in memory amount will give very different hash rates when you start to get up there in N factors.  My R7 240 4 GB card is significantly more efficient at mining YACoin than your 290 because you've got to run a lookup-gap somewhere around 8, where as I can run a LG of 2.  You may need to do something like coinwarz does where you let the user input various hashrates for different coins

@Thirtybird
At one point I have considered to not disable other inputs and let users do what they wish. But that created a problem.
Lets say you are interested only in chacha mining, in comparison with scrypt coins. You enter your chacha hash rate, scrypt stays default 1000 and the list is not valid anymore. If your chacha hash rate is more than it would be on normal scrypt(lets say by a factor or 3). You now look on the list and think "Woow all those chacha coins are so profitable compared to regular scrypt".

You did raise a valid point though, I did not know that low-end card with a bunch of memory can outperform high-end with smaller RAM the same amount of RAM. Something to think about definitely.

How about a 7 day most profitable average for all the coins? Or maybe even a 30 day average?

That'd be a great addition.

@acuriousman Will consider that when db catches data for that timeframe

@LuckyBtc Do you mean coin logos? they open fine on few of mine computers, anyone else having problems?

Thanks! Currently I am looking into Hiro, dark, heavy and myriad.

That would be most welcome Can you pass me a link in a personal message?

Well i didnt say that ultracoin is the most profitable to mine of all coins. Some coins will be added, but not during this weekend. Not sure what you mean by that database thingy - are the scrypt-n and scrypt-jane values not correct for you?
