Paid placement on the site?

Is WhatToMine.com wrong? That is my question

I have 8 1070 GPU's with combined power of 3600 Sol/s.
Using dstm's miner on several pools I always get less than calculated on whattomine.com. I'm talking about 30-50% less.

Example:
Mined ZCL on zclassic.miningspeed.com for 7 days.
I got in average 0.17 ZCL per day.
But whattomine sad I should get something like 0.29 ZCL in average for that week.

This is -0.12 ZCL less, and that is a big difference right?

How come i have such a big difference?
(WhatToMine calculation was made using $0 electricity cost)

This is my miner on that poll (mining for 24h right now)

Can someone please take a look what is wrong?
Thank you all for support!

 This difficulty at PIRL doubled almost overnight. Whattomine was cool at first but I can hardly stand it anymore. Whattomine ruins every opportunity by giving people the tool necessary to see when they should switch coins and start mining long enough to increase the difficulty and then leave everyone that was originally mining that coin faithfully left stuck mining at a higher adjusted difficulty while the whattomine bandwagon goes to another coin to raise the difficulty of it also.    Then it washes and repeats thus exploiting the difficulty of every coin and that gets my attention. The kind you dont want if you run a website.

 Workable Solution - I wish every coin was like proof of research similar to GRIDCOIN. Not only because it is actually a productive coin with purpose but more due to the fact that you earn more the longer you mine with it due to "Recent Average Credit & Magnitude" factoring in on your income. I think mining income should be 1/30th on day one. 2/30ths on day two ect until reaching maximum potential of rewards at the 30th consecutive day. For every day that no mining on that coin takes place you lose 1/30th of your potential. Its fair and simple.

Personally I think that some kind of filtering of coins is a good thing.
Lets not try to list every coin out there

@Rampager
Well we cant deny knowledge to our great community
Interesting income schedule, would certaintly stop coin hoppers.

No docs.

Its multiplied by 3600 cause the value returned is for an hour of mining. For a day of mining you need 86400.
Nethash is only an estimate, this value is never real and yes the real mining formula uses difficulty - thats the value relevant to finding a new block.

Block_reward is always per block. The formula just needs the number of seconds for which you want to calculate.

Both estimated_rewards and estimated_rewards24 are 24h estimates. The difference is that 24 uses difficulty_average_24 and the other uses current.

Hi(noob here)

I really want to congratulate you on a great site. I find myself using it quite often to calculate profitability for coins

I'm hoping to make use of the JSON endpoints and have some questions regarding them.

First off, most important, fair use policies. I respect your work and don't want to be that guy that hits your API unnecessarily. So, here are my questions regarding that.

How often should I query the respectivecoins.json,asic.json, and calculators.json endpoints?
What is a good refresh rate for these endpoints from third-party clients?

To partly answer my own questions. I read on this forum that the rate limit is 80RPM and the coin data is refreshed every 3 minutes.
One more questions about the rate limit. Is 80RPM limit per user/IP across all endpoints?

I've noticed that there are JSON files for the following:

GPU - http://whattomine.com/coins.json
ASIC - http://whattomine.com/asic.json
Coins - http://whattomine.com/calculators.json
Individual Coin - http://whattomine.com/coins/192.json

My guess is thatcoins.json andasic.json gives you all the GPU and ASIC coins on Whattomine form what I could gather from the website links. From here you can determine, by looking at the data, what coins are profitable to mine. See my question about "profitability" and "profitability24" below.
A good workflow would be to cache coins retrieved from these endpoints and then once I have determined the best profitable coins to mine, I build the URL to an individual coin(in your language of choice) from the subset of data and request the data fromcoins/<coin_id>.json.
These results need to be cached, and the cache warmed up, all the while respecting your API's fair use policy.

How am I doing so far?

"profitability" and "profitability24" values.

It seems those are percentages. Am I correct? What percentages should one look at here? Is 100% and above considered good profitability, or are there other percentage ranges to consider too, for example, 110% - 125%?

On tocalculators.json.

What does the "lagging", "listed" and "testing" values mean in the response tocalculators.json?

I had a look at a coin called Aeon, and although it's "status" is "Active" the "listed" value is false. I don't know what that means.

What does "testing" indicate? Does "testing": true mean you are testing it?

My following question pertains to the estimation calculations for a particular coin. Let's stick with Aeon to simplify things. Only because I have mentioned Aeon above.

These stats are fromhttp://whattomine.com/coins/192.json, which also reflects the data on the web page.

So, I gathered that the following values correspond to "Day Rewards" under "Estimated Rewards". See my questions inline with the JSON values below.

Very best
