After emailing with Wyeast a few years ago the only time I decant is if I am doing a delicate style or a volume that is approaching the limits of my fermenter. For 20 gallon batches I generally make a two step, two gallon starter, beginning 48 hours before brew day, on a stir plate with constant O2 feed.
The Wyeast pitch calculator is a great tool:
I have to agree that this has to effect the final beer. Do you account for this in your recipe? A two gallon starter has to be about 1.75# of DME?
I definitely pitch some of the beer but decant as much as I can.
