Saddle tilt--adjusted differently on trainer than on the road?

[VeloVT]

I dunno about you, but my tilt adjustment is a very very precise thing. Once its good I don't want to mess with it. I mean 1 millimeter higher or lower w/ the nose makes a huge difference.

Changing the tilt would be like remodeling your house just to get a picture to hang straight.

+1. I'm super fussy about saddle adjustment and once I finally get it just right, I don't want to move it .

However, I understand the impulse. I do think riding the trainer is tougher on ahem, the parts that contact the saddle than riding on the road. I definitely move around a lot less, and I think there's more "sitting" going on -- that is, I think when I ride outside there's much more weight supported by my pedaling and upper body than when I'm on the trainer, and on the trainer most of the weight tends to be on the saddle.
