Seems the opposite to me. Shall I show the whole email? Braiins has always been very transparent. I can tell you as a long time part of their pool that rewards have been rather inconsistent lately and this is a good change. In their email they also inquire if pool participants would still like to see another pool with the old payout methodology or even a solo mining pool from them.

Yes, I actually wrote them a support ticket asking if they will be providing more transparency about payouts in the future. This random stacker news comment provides an argument for why FPPS might not be good. The old scoring system was relatively easy to understand and the way they calculated payouts was transparent. It only becomes inconsistent if the pool is losing hash and isn’t consistently finding blocks. In the new system the volatility of inconsistent payouts is shifted to Braiins and we have to trust them to properly manage their reserve AND tell us what a fair payout is.
