It matters not a jot how many times your pipe needs to be relit. Pipe smoking is hopefully a relaxing pursuit, not a competition. If you are stressing over this to any degree at all, you are missing the point. Enjoy (and celebrate if you are minded - these are rare events) a "perfect bowl" by all means, but so much more goes into that besides simply saving on matches or lighter fuel. Some smokes are "just perfect" despite numerous relights.
