Im in pool 2 and so far I see pretty steady results. Unless a big dog comes in and houses stuff for about an hour then leaves. i was getting about .6 a day. I have been watching pool 3 and it seems to be picking up but not sure if I want to jump just yet.
I think you should, for 3 reasons:
1. Current pool hashrate should get about 1 block every 1.5 hours. So it is quite steady.
2. I have this theory of double rewards.
N = 100k has the same hash as 2 blocks. There's a probability you will get rewarded twice from the same share you have done.
example:
If you get 1% of roundshare for the first 50k, when the pool definitely find a block within that 50k, you get 1% x 6 coins,
You continue to work on it for the next 50k, and get another 1%, your reward will be 2% x 6 coins.
3. More hashrates will make this happen sooner, before the pool owner changes it.
