I have a quick question about the following API call:

https://miningpoolhub.com/index.php?page=api&action=getminingandprofitsstatistics

This API call returns some great information about each pool. I would like clarification on what the units and time frame are for the following fields?

"normalized_profit": 0.05755849,
"normalized_profit_amd": 0.0281461,
"normalized_profit_nvidia": 0.08190574,
"profit": 0.05755849,

It seems from some previous conversations, the profit is "per 24 hour period" - is this correct?
Also, is the profit in units of $$, coin, percentage of coin? Any ideas?

Finally, is there an individual "profit" per USER available in another call? It does not look like it.

Thank you!!
