I don't think the question was regarding how tall the drops sit above the playfield, rather when they are dropped they now sit an additional 1mm lower. Causing a larger gap between the top of the dropped drop target and the top of the playfield. Probably not a problem for most width-line? side-by-side drops? (I actually don't know the term for drop targets spread out width-wise) banks, but I would be interested what happens for in-line drops. Probably enough adjustment in the drop target mechs, but will be interesting to see if there are more hangups as a result. Don't take this as a warning or complaint, as I think this is a great product intended to be an economical restoration solution for games that normally would not be justifiable in spending 800+ dollars on a new playfield. I would buy a paragon today if available.
