Where as fourth gear, I believe, would get the car up to 50 much more efficiently.

My thoughts (and actions): I do a 5th gear 35-50 P&G routine every day. I think it works well.
I use ~75-80 LOD, up to 90 at times. Above that and it goes into open loop mode, dumping extra fuel in to keep things cool.
