I'd just like to compare the strength difference between various insei leagues, I know a little about Japanese insei, however I'd like to find out how strong the bottom of the E league is in EGF DAN's (around EGF about 3 Dan?) and the top of the A league (can't decide betwee EGF 7 or 8 Dan) and everything in between. I suspect the Korean and Chinese top class insei are 0.5~1 stones stronger than top class Japanese and Taiwanese
Note: In short, rank, in reality, is just a number in front of a name that shows the most likely level of decision making in a go game compared to other players, and because the arbitary and semi-absolute value of rank, it can be tricky to discuss rank.
I use the EGF standard when talking about Dan grades above.
