Officially his ratio is 0/0 since he has not participated in any KeSPA sanctioned matches after he got his semi-pro license (It would show up as a 0% rate for wins and losses).
I'm not entirely sure he would appear in the KeSPA since I think they only do full professionals only (having a license and being registered with a team). Even if they did, he doesn't have any points so it list him as dead last.
