This thread covers a lot of material but doesn't answer many concerns. Here are some technical questions that surely someone know the answers.
1) let's say a GBLE owner bought a spare playfield that currently sits next to his machine. Should both playfields act the same, ie if the playable one starts ghosting, it would because of chemical reaction of the paints or temperature shifts, not caused by ball rub, so the spare playfield would be just as susceptible to ghosting, right?
2) ghosting is primarily an issue with GBLE games having been run over past few months. No other title is experiencing the same wholesale issue, including MMR, right? Other games are getting made by Stern without the ghosting,including GB pro and GB prem, right?
3) if your GBLE playfield should start ghosting, you could fix it by swapping in a new playfield, but could you sand and reclear your existing playfield to fix the problem, right? Don't understand if this would work as a practical matter or if iother factors would prevent it from working.
