This sounds quite similar to dirac which made a stir a few months ago:

I spent way too long trying to reproduce the results in Pi and failing before I decided that I shouldn't trust author benchmarks for any of these tools. Then I found that I couldn't even close to reproduce their benchmark results using the exact model and their harness.

If any person other than the author has time to verify these Lumen benchmark results I'd be curious to hear it. I don't have the time to do it myself at the moment.

I did the same with another project that does the same thing, called ck, and wasn't able to wring out any improved performance over just plain grep.
