Dont take this as an attack, but actually this means very little. JP Salas is probably one of the greatest table authors on VP and has years of experience with VP and he has limited skills in setting up the table physics for his games.

That is a skill in itself, and probably the single biggest weakest link when it comes to Visual Pinball. Its not that you cant do it, not a lot of authors spend time on this stuff, yet alone the people that are downloading and playing their tables.
If you know what your doing you can tweak a game to play very similar to its counterpart. You can also tweak a game to create more of a keystone effect-- added depth/realism , very easily as well, but few people do it or know how to do it.

I started off doing kind of what you are doing now, using a single screen, then evolved and built a bad ass Vpin:
http://pinside.com/pinball/forum/topic/fs-virtua-pin-tm-big-bang-pin-virtual-pinball

I have helped contribute physics settings to two of the top three virtual pinball authors-- Groni-- Banzai Run; Uncle Willy, BBB.
You can go on VP forums and google "layback or keystone effect", I wrote the first article on the discovery on how to tweak the settings when VP 9.XX came out.
There is a lot you can do in Visual Pinball, you just have to know how to use it.

I do also understand about the burnout over time, mine was kind of different, but I understand were your coming from.
biggest down fall to VP pinball, is knowledge and getting everyone on the same page.

Again, we are going to have to agree to disagree. There are more settings than just oblique to get more accurate flipper settings. Instead of looking into the code, you have to take the settings you have to work with and experiment and spend the time making adjustments; the good thing, most of the settings will work on other tables. Flippers are also preference, I like mine set up a certain way, and Groni and Noah Fentz both liked theirs set up differently.

There have been a bunch of VP developers that have came and gone, even the great VP developers (Cupid) still didnt know exactly how to maximize most of the adjustments in the software tool.

Again, I will say this respectfully, but again we will have to agree to disagree, and I am a competitive pinball player inaccurate flipper settings will not fly with me. I will say this is Not one of the limitations of VP pinball.
I can also do all kinds of flipper passing, post passing etc... just like the real machine, if the flippers and flipper rubber (elasticity, etc) is set up correctly.
