You just need to calculate net profitability, i.e. excluding rejections and fees.
net profitability = gross profitability x (1-fee) x (1-rejections)
For your example (I will average the rejection rate):
1st: 104⋅(1−0.02)⋅(1−0.015) = 100.3912
2nd: 117⋅(1−0.02)⋅(1−0.05) = 108.927

In this case the second pool WAS more profitable in the observed period. I uppercased 'was' because past profitability is in no way a prediction for future profitability. One pool can have 120% LTC profitability in a given hour and 80% prof. in the following hour. It is just luck. Rejection rates are more stable tough, so try to avoid pools where you get high rejections.

But wait a minute, what about the Ping doesn't this affect accepted shares also??


Edit: New server I hear??! Hmmm must try this soon hopefully rejects drop

But the interesting thing about this is, I have had reject rates higher with certain pools with ping around the same.

Example -

1 pool 230ms = 6% reject

2 pool 230ms = 3% reject


Ahh Ok I think I see what you mean..... All you need to look at in calculations is Accepted - Rejected... Ping can be what ever it wants ? DOHH

I am mining with two gridseed G-Blade. It starts really good, but after half an hour the pool difficulty rises to 2335!! and i don't get a single share anymore. What can I do?

My Username is : 1ExxrRYFVqFiT2PiUQppsxhk5aSBYAuEyT

But I just restartet my rig, so the diifficulty is down to 512 now. But I already tried a few times and the difficulty always rises after a few minutes. And I waited for like 45 Minutes and it didnt went back down.

Edit: Its already up to 1990 after 2 Minutes

I was at 19000 just a minute ago, it's screwing with my auto-restart cause my miner thinks that blades are going down when in actuality it's just taking a long time to solve a share.

What happened to fixed diff at 512?

Hm. So before, people complained about not having vardiff, and then that there is fixed difficulty.
Now, one 512 share = 512, one 1 share = 1, one 1024 share = 1024.
So 512 difficulty one shares equal 512.
If you still don't understand, it means that there is no difference.

No it's not, because stales are also paid for.

Later on it went to 657, then 1292. Everything works fine.

I can imagine than your miner can get extremely lucky and solve a lot of shares within a short timeframe and get high difficulty in result. You don't need to worry about it, because it will take you longer to submit this share, but it will be proportionally more worth. And you diff will go back down after couple of minutes when the pool detects you send shares infrequently.
