Sorry, I know this is a week old but I don't get to post as often as I'd like to.
I'm not saying your math is wrong but a 10% decrease in height only, on a three dimensional castle would be a 10% decrease in overall size -- A 10% decrease in height and width would equal a 19% decrease in overall size and finally a 10% decrease in height, width, and depth would give you the 27.1% you posted.
Not saying that isn't gonna happen, but you can't use that equation on the castle with a reduction of only one dimension.
Come on, cut me some slack here.... My mommy says I'm smart![]()
