I think what he meant was the Coin per Day per TH/s has been decreasing as you get closer to present time:
0.00018586 CDT for Quarter
0.00014460 CDT for Month
0.00011849 CDT for Week

I don't think he means that, since, according to the data in the webpage, Kano pool is decreasing even more rapidly, having into consideration that kano is 0 CDT for this last Week (not n/a as is written in there... correct Week CDT for kano is ZERO)
But if minergain.com means that, then the question would be: Slush is decreasing its CDT rapidly compared to which other pool?
Yes, it is all very confusing - and you are right, I will change the n/a to 0 in a bit since it is actually 0 for the past 7 days.
Obviously the weekly value is very meaningful on slush since they get tons of blocks every day now. The Kano weekly is not really that meaningful due to our low hash rate / variance. For example, if we get a 15BTC block right now, I estimate my S9 reward will be roughly .00055BTC. If I have my manual calc correct, that would make the weekly CDT equal .0000582. Hitting 5 of them in the week like we did a couple weeks ago would make it somewhere near .0003. So yes, if you are looking to stay at Kano for a week or two, this is not the place to be. The difficulty is the biggest factor on the difference change, but if you look at the Quarter to Month, the decrease is more pronounced on slush. Ok, now that I am blabbing about this, probably best to forget about it since it is all determined by the blocks we find.
Maybe I will just say that I am here because I am "gambling" on bitcoin, and I have much better odds of winning bigger here where every block that is found has a much bigger reward - as shown by the yearly CDT. So what those numbers mean is that every S9 running at 13.5Th/s for a year, you would get about 8% (.153984) more BTC by being with Kano ($2,300 additional at US$15,000 per BTC).
probability is a bitch and it plays with all of us... To say that Slush is decreasing rapidly might be right... but as it is as right as your good luck depends on my bad luck today, but tomorrow is a new day and tomorrow I could win... and then you will be the one decreasing rapidly.
I mean, even saying: "..weekly value is very meaningful on slush since they get tons of blocks..." I believe that bad luck lasts as much as it lasts... If you go to the historical data at minergain.com you will find for sure weekly CDT with greater value for slush than for kano, surelly it could even be found monthly CDTs following that condition. it is more rare, but probability is a bitch! I mean, permanent GOOD LUCK or permanent BAD LUCK doesn't exist in probability...
