Your rendition of the table is spot on!
I actually played the real one for 10m yesterday. Unfortunately the deal was not done but I retained a few things between playing and chat and my 20years or more handicap since I last played a real table :D
The manual specifies 6º so I'd say that one was setup like that because it looked pretty flat. This means it's a slow table.
The left ramp is nigh impossible to do from cradled ball on the right flipper and it'll require a bit of momentum. Coming from plunger, a.e., is easy to do it all the way up. Strategy wise it's a problem because its the jackpot's ramp
Otherwise, provide one's accuracy is ok, everything is in reach easily althought the flippers felt underpowered. Again, it is an old table and because was in pretty good shape and revised recently too I believe it's how they supposed to feel and it played like YT videos too.
The left slingshot in particular tends to send the ball to the right out lane so nudging will be needed

Regarding VPX, I've installed it and the table you provided and I'm not sure exactly what you need. VP uses roms so, reading the manual and code that should be accurate. I already skimmed through it and i'm confident I can test whatever you send me and even code a bit in case I find something and then send it back to you.
Physics wise that VP version it's too hard to hit ramps and /or "loop" lanes in comparison to real table. I feel the flippers have too much power and way too eager to send the ball to the center of the table. In the real one you can pickup the aiming points and repeat the same shot almost at will. In this VP table the more you are away from center shots the harder it is to make a shot consistently making those drop targets harder then they are. Something to look forward in your version and something I can help with I'm sure now that I played the real one.
In any case, if you need something i'm here. I'll do my best.
