The reflex it has in the moment will probably disappear after you have tillered the bow. It's still a good thing to have reflex though, as for example: you have a stave that is dead straight, after tillering it has 1.5" of set. Then for example, all things being the same, you have a stave with 1" of reflex, after tillering you may have 0.5" of set. Hope that makes sense
