Here's where I'm sitting and why I backed off from Slush for now... I am currently profit switching with AwesomeMiner between zpool/NiceHash but I may end up coming back soon. I was getting better numbers when I first started but the pool hash rate jumped considerably shrinking my share per block. I was, at one point estimated to get my 0.01 payout every 3 days and 4 hours but when I left it had extended to 4 days. My payout per block started around 0.00018 to 0.00023+ but when I left I was getting 0.00012 to 0.00014.

1-S9
12/18 - 12/26 (I took into account only the blocks where I was over 13 Th/s). There were moments when I left and came back or was ramping up/down but I counted only blocks where I was hashing at full strength.

132 - Blocks I worked on (100%). 2 of these blocks were invalid.
1.521 - Eh/s Average pool hash rate for those 132 blocks
13.45 - Th/s Average for my single S9 for those 132 blocks

0.02119930 - Total Payout
0.00016060 - Per block
690,502 - Total seconds (7 days 23:48:22)

Taking the amount of seconds totaled and the amount earned I have these numbers...

0.03 - per minute
1.55 - per hour
37.14 - per day
259.95 - per week
1,126.47 - per month
13,517.60 - per year

I am well aware that a year from now I will not likely be getting the same numbers as more miners are added and my hashing power counts for less as well as difficulty. I took the time to put it all into a spreadsheet so I thought I would share. I'm still new at this so I watch everything like a hawk which is frustrating AND fun at the same time. I'm sure after I've been at it for a while I will be less shifty based on some bad days here and there or some really good days on a pool I'm not mining without feeling like I need to jump so frequently.
