Well, if you want to find out, mine against your own pool. Its not like there is not a pool operator posting here for some reason...
The fee is 2.5%, this is immutable and hard coded. For S9, it is 2%, also hard coded and immutable. There are no choices of changing this. Unlike other firmware, you cannot add hidden groups on top of the existing one by request, whitelabel, or whatever.
Point it to your own pool locally and measure, you will get either 97.5% or 98% of the hashrate. The miner dashboard reports 100% (Real) hashrate, the pool will only get 97.5% or 98% from that.
If you add groups and assign a fixed ratio, you will notice there is a hidden group always taking 2.5%, so you only have 97.5% available to split. Its not 90%, 95%, or whatever random fake account of the month decides to invent because they don't like when i point the fact that all other firmware infringes cgminer license while Braiins doesn't. Too bad that pool operator doesn't care and prefers to join the badmouthing crowd without proof, as usual.
Farm proxy is another project, and has a different license. It has no fees, can be used without Braiins OS.
None of what you said answers any of the questions I posed in the original post. My post covers communications with your team and your very own license that disputes everything you just said. I can only assume you 1) didn't read my post, or 2) know exactly what you're doing and giving a politician-type answer - not answering the question and just repeating numbers, as Kano said.
Again, why not simply make a feature in Braiins OS+ that SHOWS where your hash rate is going and how much? Wouldn't that make everything a lot simpler? Or is it because you take 10% dev fees (or more, who knows? its closed source) according to your own license that I had to spend 2 weeks getting out of your support team.
