A little more clear math would be appreciated... also a numeric result is expected.
Although not exactly what you are asking, if you check out the home page (of minergain.com) you will see a CDT (Coins per Day per Th/s) for Kano / Slush that is updated every 15 minutes for the past week, month, quarter and year. Some of these are hidden on mobile phones so use a desktop to see them all. Obviously this the past - which has no impact on future "randomness", but should give some idea what the long term results may be. The one big thing to notice is how rapidly Slush is decreasing.
Thank you for your very good reply. CDT is even better argument :-) I was calculating CDT ≈ 0,00016 for slush in January 2016... but well, looks like I was a few optimistic (and probably wrong!) :-)
What I don't understand is: "The one big thing to notice is how rapidly Slush is decreasing."
Do you mean from "profit for miners" perspective? and from where you notice that?
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?
