I average around one or to shares a minute, but sometimes the thing says 450 shares found or 30 shares found and my score has been as high as 30mil with the total score being a few hundred mil so it's more of a ratio of my score vs the total score as well as the number of shares. trying to figure this out and the fact that i'm not a math type nor a programmer it takes a little longer for me to grasp it.
Sorry but no. If you are submitting 2 shares on average you are at 100+. You might get them sometimes but on average you shouldn't.
About the score. Every share gets a time value and is added to score. More time the round takes the higher is the time value. And that is the only ratio that is important. Total score vs your score. EDIT: Forget shares. After being converted to score they are there just as a data for you to see and figure out if something is wrong.
Just adding this. Sometimes it happens that score number becomes extremely big and it needs to be reseated. That is why the score can get smaller during of the round.
