What are the columns "mu time" and "sigma^2 time" of thebenchmark table in the Sampling subsection?In statistics mu is often used to describe the average, sigmathe standard deviation and sigma^2 the variance. It wasabsolutely unnecessary to use this notation here (especiallybecause standard deviation, not variance was measured). I fixedthat and also added how many samples were generated per run(10M), thanks!

Thanks for the clarification and the fix.

`(I am familiar with the usage of mu and sigma, but somehow I`

`first thought that the columns corresponded to two different`

`measurements. After the initial confusion I realized the correct`

`meaning, but still wasn't sure about it due to contradiction`

`between the name of the column (sigma^2, not sigma) and the`

`values (ms, not ms^2 or something). So I thought that it would be`

`Another question: You mention that statistical quality is`

`important, but it is not clear if flex has better or worse`

`quality than Box-Muller and Ziggurat in the case of sampling from`

`normal distribution. Or is the difference negligible? (I realize`

`that the real strength of flex is its versatility.)`
