I can't speak for Rudi, but for me the concern is not about the (ultra) high scores, but rather the product is not what it is pitched as.
These guys endlessly drone on about how fanatical they are about replicating the real thing right in your home, but never with the caveat that the replication extends primarily to the table facade and features ... not truly a genuine simulation of the physical product (which they nonetheless purport to be).
Quotes from their KickStarters, emphasis mine :
We want our videogame version to play exactly the same as the table played when it was new, so we start with a thorough restoration of the table.
We’ve created ROM-emulation technology that allows the same program which controlled the original table to run on our target devices. This means that every rule, sound effect, and light sequence is exactly correct in our digital version.
We’ve continuously improved our pinball physics engine for the last seven years and we’re very proud of it. We can individually control reflection angles and physics parameters for every section of any component on the playfield. We use the original table as reference when doing this to ensure accuracy.
The end result of this painstaking process is an exact digital recreation of the pinball table that you can play on your handheld device or in your living room.
It's always a disappointment to buy one of these tables and flip half to 4/5ths the table goals in the first game.
Despite all their ballyhoo over ROM-emulation and awesome lighting engines I still contend the older Hall of Fame collection plays (and looks) better than these new tables.
Still my biggest disappointment of the year.
