Surely the table is more conservative than the VR3? If not, is the factory default setting very conservative?
It does depend on what kind of dive you have done. As computers multi-level, whereas a dive table assumes square profile, computers often appear to be less conservative. However the algorithms are often more conservative. If you do a square profile dive the VR3 will usually be more conservative than a (sensible) table.

If a stop is missed on the VR3, why doesn't it recalculate and penalise me with an additional stop or longer time a shallower depth?
Because it would be a BIG GUESS. The Vr3 just gives you Buhlmann and lets you add the big guesses yourself.

It just doesn't feel right on a 50m dive using a table that a computer tells you to go deeper and stay longer.
The VR3 will usually give deeper deep stops than gradient factors so it is not suprising. Set your deco program to GF 5-80 and see what that looks like.

To be honest, the VR3 scares the shit out of me more than the Inspiration!
Then you don't full understand your Inspiration.
