Greetings...Neither Linda, my Teacher nor myself use Chiron. That is not to say that it does not have some small role to play in a chart interpretation, but none of us feel (or felt) that Chiron was to be considered a ruler of any sign.
Modern Astrologers seem to be in a rush to allocate "rulerships" when they have not had sufficient amount of time to do proper study and research. What they may note is some "affinity" of a planetoid or comet or asteroid to a particular sign, but without years of research and study, I think it is ill advised to begin eschewing the tried and true "Rulers" for these astrological new-comers.
So in that regard, I cannot presume to speak about a number associated with Chiron, as I have no knowledge in that arena. I have yet to see any astrologer tell me anything about myself or anyone else that cannot be determined through the use of traditional Astrological methods. (the 10 Planets, the 12 Signs, the Aspects and the Houses) There are mountains and volumes to be written yet about them... let alone the flotsam and jetsom of deep space.
Best Wishes and blessings...

P.S. Why would anyone want to see a "wounded healer"? I want mine to be well and whole so that he or she can assist me in making myself well. I wouldn't care to be operated on by a wounded surgeon, nor have my teeth poked, prodded and explored, let alone drilled and filled by a wounded dentist! Make any sense?
P.P.S. To forestall any claims that Linda may have used Chiron or any of the asteroids when she did charts, I know she didn't use them as I worked with her and discussed the matter with her in some depth.
