Thought I'd ad something to the Leetpools discussion.
These are my own thoughts and theorys, so correct me if I'm wrong.
The blocktime on UTC is fast, and both Leetpools and Nitro uses Prop payout (right?). So for you to get what they predict you need to have shares in every block they find. And blocks can be found pretty fast on these pools, so you'll miss out on quiet a few of them because the vardiff is actually set too high.
I also thought I got too few coins on these pools, so I changed to greekpool as my primary and Leetpools / nitro as backups. Smaller pool = more time to get shares in between blocks. I also got better results on Greekpool.
Any thoughts on this?
