That is fair. Well, maybe you could just add a small note in the book that states the ratios aren't accurate 1:1? As a placeholder for now, anyway.
Wait… We can modify the game after it has been submitted?
Oh, I somehow missed it on the rules. Let me make an improved version of this for other players as well. Thank you for bringing this to my attention.
As long as you keep the original submission as a downloadable, that is fine from what I've read on the rules. Go for it!
