US kill loss ratio versus Russian pilots in Korean War?

US F86 sabres shot down a lot of Mig 15s in the Korean War. The ratio was
around 8 - 1. I recently watched a documentary about the confrontation
between these two planes. Apparently they were quite evenly matched with the
F86 having a slight overall advantage. In the end the high ratio was
attributed to the superiour skills and experience of the US pilots. Many of
them were WWII veterans while the North Korean and Chinese pilots had bugger
all experience. However what was interesting was that some Russian pilots
also flew against the US. Does anyone have any accurate records on what the
kill:loss ratio against Russian pilots in the Korean War were?
