I saw the review where it was stated the kit is accurate for Kronzprinz post -Jutland only. I have both Konig and Grosser Kurfurst in my stash, and plan to do one pre and one post Jutland. I've yet to research the ships myself, but here are some sites where you go do some of your own research:

There is also a series of build up article on the Konig by Andy Elwood on modelwarships.com, but sadly it's incomplete:
