I'm sure year one will be rough by gopher standards with improvement in year two, peak will be years 3-6 with slow decline after, probably similar Bobs arc, but if Bart gets a Natty at the peak, he can survive the first valley like Lucia did, or like Brooks did in 77 and 78. Woog run from 84-85 through 96-97 was the longest sustained period of consistent success just didn't win the big one
