I think if you can get 100% accurate deltav out of the gate it means that early missions aren't as experimental, and it makes the game a bit too easy.

I'd say yes, but with conditions. My initial thought was that deltav could be rounded to 2 significant figures, say 860, 5500, or 11000. That would negate some of the negatives of showing deltav, and as a mission proceeds and the amount of remaining deltav diminishes, then the accuracy would shift once we hit sub-1000, or sub-100, which feels realistic. The degree of rounding could be tied to an upgrade in the KSC.
