Default The K Factor

can you guys give me how you get your K factor? I have been reading about it a lot and it seems that to start the K factor would be t/T t=half of the metal thickness and T= Metal Thickness.

So would the K factor for .135 (10 gauge) be .500 ? did I figure that right?

the engineers at my company told me they figured the K factor by punching in numbers until they came close to a 80% bend allowance and not by reverse engineering for the K factor which left me scratching my head and refiguring all the cut sizes for the 10 gauge parts before I break because their drawings are wrong. for the 10 gauge they came up with a 54% K factor. now I am not sure how the % works in AutoCad would they be using .540 K factor? or does it not work like that?

any help with this would be great
