That's to comply with ANSI! And FNMA demands you follow ANSI...so you do it by the book, waste about 10 minutes to Gawd only knows how long if stipped - only to achieve absolutely nothing in regard to "accuracy"... precision yes, accuracy no. And split levels and ½ stories will be forever problematic, time consuming and you can bet your bippy that no hybrid inspector will measure to ANSI so WTF? Another Fannie Mae nothing burger. " A tale told by an idiot, full of sound and fury, and signifying nothing."
