I understand the reason for doing it, Davis is a nice place with a lot on the immediate vicinity of its old SP station. Plus literally just minutes west of Sacramento. But can you do a guaranteed connection 11 to 6 connection there? Once upon a time you could do a guaranteed connection west of SAC, but Amtrak appears to have shut that down years ago.I like making the Train 11 to 6 connection in college town Davis, but I'm familiar with the area and I do it on my homebound trip, so if something goes wrong, I could deal with it. I wouldn't recommend a same day connection west of there.
Personally, I am really allergic to same day non-guaranteed connections.
I actually somewhat allergic to some certain same day guaranteed connections, as I am very protective of sleeper accommodations. Like eastbound through Chicago. But that's just me...
