On one of my pools or miners i used to track highest difficulty share mined per second or something and chart it on a graph.
I know itd be pointless, but maybe a fun way to "pass the time" to show a graph like that. Plus then we could all get angry about how close we get to solving a block.
Just an idea I had anyway.
If the data was available thru an api I could throw something together.
If you submit 1000 valid shares, and your work difficulty is X, every one of those shares is worth X, no matter how high the difficulty is.
As long as they are X or more, they are worth X.
This is how all reasonable and fair payout systems work.
Any other valuation of shares adds yet more variance to your rewards and allows people to take advantage of that.
Many people look at the "best share" value and assume it means something, when in fact it means nothing at all ... unless it's a block.
You miner knows it's "best share" if you are curious to see what it is.
However, I do store every share above a limit for my regular statistical analysis, but no I wont be showing graphs of that.
