Trouble about your real yield or about rewards directly

Hello, I just looked and the polkadot staking rate is 14.5%, you displayed 17.57% - 0.25 for the VDOT farm so we are at 17.32%. Assuming that you take the 10% commission provided, this gives 17.32 - 1.732 = 16%.
There is therefore a gap of 1.5% with native staking on Polkadot JS. Are you paying for your surplus by converting BNC or is the yield just plain wrong ?

Likewise for my case, I do not give the amount of min staking but you will deduct it, by applying 16% yield to my current LST VDOT I should have around 1.3 DOTS per day by multiplying the yield percentage by the total of my VDOTs to have an annual results which I divide by 365, simple reminder here.

I know that the validators are rotating and do not apply the same commissions but it is between 0 and 3% for you if what is displayed is true.

But if I set myself at 14.5% that gives me 1.18 minus 10% and so that's right with what I get today 1.08.
Good! This is a daily example subject to variation over time, nevertheless, it speaks for itself.

For more transparency, it would be good to display a real rate of return closer to the real staking rate here 14.5% deducted from 10%, so 13%, which is clearly my case.

If this is not the case, and I have done the calculations so that it is, that means that someone else(s) is taking this surplus. And in this case, that means I lose more than 0.2 or more than 20% of my rewards and this is unacceptable without justification. And even more 30% if I take take into account your 10% commission already deducted, is clearly enorme.

Really, the difference between what is displayed and what I receive is too great and I have noticed it for a while.

If I expose it in the discussions it is so that this comment can be seen by everyone, no need to go to discord or anything else to get pseudo answers or non-answers or very evasive ones.

With DOT inflation, there is already a significant dilution of value, so my criticism also relies on this point to force transparency, or more reasonable transparency than it currently is.

So, please, try really be transparent. Because this trouble begin really to give me personally a trouble and I know do staking by myself!

Just be clear about Yield, and here the yield are not clear at all for me and the gap between what I get and what should to receive is very large compared to what displayed .

Thank you for your attention
