Western Rustic shrink wrap bag sizing

[retlaw]

This is the first time doing this bird and was wondering if anyone else does them and has info on the finishing weights and shrink wrap bags sizing.
The breeder said 5.5 lb at 9 weeks.
Is that what others are getting at that age? Dressed or undressed?
And info on shrink bag sizes to weight and age?

10 week roaster (WR) dressed 5 lbs bagged nicely in a 250mm x 450mm shrink wrap.
Still had room for my hand so the bag will do a bigger bird.
Bags shrink 30 to 40 % I was told.
