I have always gone along with the idea that some might think that a Modeler is being judged instead of a Model
Since the criteria is the construction of a box of parts, and how well it is done,,,,,,,,,,,one has to conclude that the Modeler is the one competing with other Modelers,,,,,,that was how it was designed from the start
any modern attempts to somehow separate finished Models entered into the competition, from the Modelers that assembled them,,,,,,,,,is not exactly in the spirit of "I won the 2007 IPMS Best Aircraft" award (made up example),,,,,,,,,by that logic, no Modeler has won (or accomplished) anything,,,,,,,,,,,the magic parts in the box did it all
There has never been any confusion among the contestants,,,,,,,,they all knew all along that if Hans was given a Model to build, and Tarn was given the same Model to build, and they are on the same table on the same day,,,,,,,Hans and Tarn are competing, not Aurora 1/48 Sherman Model #13,589 and Aurora 1/48 Sherman Model # 7,549 (the Model # is which molding it was in the 15,000 kit production run)
I buy and use a lot of resin, and I buy and use a lot of Decal Sheets,,,,,,,I can make my own parts, and I can either print my own decal bits, or mask and paint what markings I need on the model,,,,,,,,but, I agree with Hans on the one big point
People should "Build Models", then compete in a category,,,,,,very simple concept,,,,,,,,,People should not take home trophies based on how many pounds of resin has replaced how many ounces of plastic on a kit,,,,,,,,,,,,and if someone has made a complete, believable cockpit from dental floss and used ink pen refills,,,,,,it should count more than when *I* "rip open the blister pack and glue in and paint" my newest resin replacement set,,,,,,,,,"getting the colors painted right" shouldn't count,,,,,,both sides of my example would have to do that
on the other hand,,,,,,a modeler shouldn't get "dinged" on his model just because he used some resin parts from a blister pack,,,,,he should only be judged on whether he was able to glue resin drop tanks on the pylons at the correct angle (if different than parallel, attach a Zerox of the proof)
