I mean, not sure if you've looked closely, but that's exactly what I had said. Kreveta is indeed around 2000 Elo points. Another thing is, I have never mentioned using SF 17 as my main calibration source. The readme says exactly what it's meant to say, Kreveta performs at ~2500 Elo when paired against SF 17, and although SF 17 Skill Level isn't that reliable, it changes absolutely nothing about this fact.

However, I appreciate your feedback, and wish you all the luck
