Manifold Vacuum Advance what am I not getting?

The simple fact about MVA is:
- has been around for decades.
- modern engines use it in electronic form. [ After engine is started, timing at idle is increased electronically ]
- people such as Tim [ Newbomb Turk ] do not understand combustion & requirements for such
- if they did, they wouldn't be rubbishing MVA
- all the people who are using MVA all around the world, & have better running engines because of it.....cannot all be wrong.
