Just makes me laugh when people try and use the top 100 rating system to add value to machine, I don't like wear but wear is not always due to amount of play but can also be down to other criteria such as playfield design (unprotected sink holes), rusty balls coupled with low maintenance (or just a Stern playfield ), the playfield either has wear or it doesn't, you could play a DM all day and all night and it would probably not wear (they just don't) couple of hundred games on a MB with no sink hole protection and you would have very visible wear.
