As an professional engineer, I like graphs, properly interpreted data, and charts for evaluation.
I look forward to the results of PDI testing the Stern glass, and do a proper scientific evaluation, side by side with JJP, PDI, and whatever Heighway is presenting.
It is not like others do not have both types already available.
I just don't feel like spending another $1100+ on four sheets of glass for games, let own $22K for all my games.
It adds up really fast.
Especially since I can get standard tempered glass local at far less than $40 a sheet.
I did buy one sheet of JJP glass, for kicks, and it was a nice change, but not really critical for games that are not using "eye burning LEDs" or some type glare directed downward lighting in a game room.
Never really thought about it again.
I do have access to a optical laboratory, but not exclusively for a hobby, as I am not even sure how I could get that to pass the laugh check, if I asked to borrow time, and I prefer not make up an excuse.
A comparison chart has to be generated, and it will seen how close the criteria matches the reported specifications.
Optical clarity is subjective, as is light transmission, unless tested.
Photos are not good sources of indication of specifications, but easier for layman reviews.
At this point, we really need this assessment based on the amounts of money people spend without asking many questions to manufacturers.
Until then, everything regarding this glass simply remains unconfirmed as marketing hype, and the ability to dupe new buyers.
As far as Stern is concerned, I would suspect this is classified as an "aftermarket mod" and a viable source of continued income, not a standard feature inclusion, in a pinball world of "less game for more cost".
In some ways, I am really starting to believe if Stern stated the sky is green rather the blue, people would just accept it as truth.
