thanks much! i'll dig into these soon, but that latter hint on 44 is def something i was wondering and glad to have the nudges in the right direction, and similarly on 39 super helpful to know what the basic strategy i'm looking for is ( and I had accomplished bullet 3 on 39 so glad to have figured that out :) )
