That is not a good idea. It will only change a few parameters and several of the objects in the table won't change. So, normally they become even more out of wack than they where before. Of course, you can get lucky, but, as a solution it is not valid. You guys need to learn to adjust these things themselves I'm afraid. There is many ways to tune physics. BOP from wrd1972 pr. example uses very different technique than most tables. You need to learn about physics collections and - without looking, most probably also script. There is a quide over at vpinball made by Rothbauerw that explains most of it, but, it is not a copy and paste solution. Just gets you closer imo.
