Im sure we all made around the same amount as you back when BTC was almost 20k and the difficulty was lower but we are talking about what a guy can make with his 50 s9s in this pool now and not what he could have made back in December, no? Easier just to give him the Kano calculator so he can check for himself: http://tradebtc.net/bitcalc.php 
I probably should not bother responding, but I am anyway.... There is absolutely ZERO chance to forecast what someone will make from mining in the coming weeks / months / years for any pool. That is due to luck, the price / acceptance of bitcoin, world economic conditions, announcements such as Elon Musk requiring payment for vehicles in BTC, etc, etc. All we are trying to do is give an analysis of past performance of varying pools to try to offer guidance and help to come up with a decision of where to mine. Even the Kano calculator is using assumptions and guesses. There are a lot of business opportunities that are better than mining, and a lot that are worse. To me, mining is a gamble (and very likely a future investment as well). So wherever you choose to (my choice being Kano) - Mine On!
