VD, yoshi, and lee figured they could swing 25. as VD mentioned earlier - that's an expected avg. having ridden a good bit with each of them and being the reason they didn't avg higher on the last century i think they can swing it. i doubt my ability to do so though, but i'm up for trying. i mean, if i get a snazzy matching kit that'll give me a lot of extra speed right!?
All sprint talk aside, a sub 4-hour century would be quite doable on that route; I do think you may need a bigger group of riders to maintain that pace, especially if there's any wind at all, since the limiting factor is going to be how much time you guys can spend resting.
I think the significant difference between making the attempt on track bikes as opposed to road bikes wouldn't have to do with sustainable speed (and I think those rollers may actually be easier fixed than they are on road bikes), but with the ability of riders pulling off being able to start resting immediately.
