The hash rate would be different at each time we execute PoW with the same hardware.
There might be a lot of factors which influence the hash rate value.

We try to measure the hash rate distribution and remove the extremely large and small hash rate.
A reliable range of hash rate value should be got with the method of Statistics.

This is what I am going to do.

  1. Get the hash rate n times -> [ h1, h2, ......, hn ]

  2. Calculate the standard deviation -> sqrt{ [ (h1 - avg)^2 + ... + (hn - avg)^2 ] / n }

  3. Show the result:

average hash rate: XXX kH/sec
with 95% confidence interval and error value (2 * standard deviation).
  1. Show the hash rate with histogram.

I agree that time to find the nonce value is probability problem, but not the hash rate, which is dependent on the implementation.

You are right.
I rewrite the title and the description of this issue.
