Tamryn is a grandmaster at "mount", but only an apprentice at "handle animal", despite having learned both at the same time, and riding nearly everywhere. This means that half the time she can't even tell her horse to sit down or stand up, despite (apparently) being one of the best riders in the Realm.
Perhaps the training speed of "handle animal" should be increased so it would match "mount" in typical usage; or on the other hand, "mount" should train slower?
