Besides the mention of the original Ruby project you might want to put a link somewhere to the project (maybe in the README.md).<p>I think I have written something like scientist4j accidentally several times but just using JUnit + Guava Stopwatch + logger + java random. If  its critical cpu path I use JMH. I never thought to package it up as a library. scientist4j is basically a benchmarking tool + unit test right? I think though I might be missing something?
