W is #6 out of 14 present economy fares -- 8 fare classes are higher. W is commonly picked since GPUs require it, so in that cases it is the bare minimum. Bump up a fare class will put you ahead of those that booked the minimum even if they booked earlier.
Exactly what I was looking for. As always, very much appreciated!
