Hi, I didn't find any good explanation on Work Utility.

ckolivas said :
Work utility is the product of hashrate * luck and only stabilises over a
very long period of time. Assuming all your work is valid work, bitcoin mining
should produce a work utility of approximately 1 per 71.6MH. This means at
5GH you should have a WU of 5000 / 71.6 or ~ 69. You cannot make your machine
do "better WU" than this - it is luck related. However you can make it much
worse if your machine produces a lot of hardware errors producing invalid work.


Then what ? I can see difference of WU depending on Intensity setting, which also change the average Hash Rate and the Reject Ratio.

- Does Average Hash Rate take count of Reject Ratio ? Should I calculate my Real Average Hash Rate by taking count of the Reject Ratio ?

- Does Work Utility take count of Reject Ratio ? Should I calculate my Real Work Utility by taking count of the Reject Ratio ?

- Which is better for stratum pool mining ? High Hash Rate or High WU ?

- How to improve the WU ?

  • of course it doesn't
  • did you even read? it says "Assuming all your work is valid work" which implies it's affected by accepts/rejects/hw error
  • what's better for mining, pink elephants or green dogs?
  • learn to fucking read. "You cannot make your machine
    do "better WU" than this - it is luck related. However you can make it much
    worse if your machine produces a lot of hardware errors producing invalid work."

It is pitch black. You are likely to be eaten by a grue.

Well that's not clear for me.

Green dog obviously

The maximum WU is just theoretical, means that you have necessarily less than this. So you can make it better.

no, you can't. you start out with theoretical WU, it decreases for number of stales/hw errors you have.
