    @jon its such a weird thing–they totally *believe* me but I think they believe me very much in a memorize-what-she-said why and cannot figure out why it happens at all. Ah well, hopefully they at least remember to do it (we focus on using a test point anyhow, so hopefully not too big of a problem)
