This was released about a week ago. Some people have asked me what it's about and how to use the file while some others may have not known about it.

This is designed by Mathias Gemuh, and it's a wonderful tool to estimate the engine's ratings in CCRL scale based on STS "Total Score"

Here is one example of an accurate STS Elo Estimate of Homer, in comparison with CCRL scale: 



The elo difference is the wonderful feature, It's good to see that estimation is mostly within +/- 100. With more STS chapters, I hope that this gap will be reduced. It might give valuable info as to how much the new version has improved over the previous one, or estimation of rough elo of any new engine while at the same time save much of the testing time.  8-)
