Extrapolated Steel Bending Values for 8-3/8" Stock

[acromegaman]

Hey everyone! I was interested in what certain bars would rate at the longer lengths so I took it upon myself to extrapolate the existing data. I assumed that adding a 1/2" increment would subtract 15% off of the bar's poundage. I have bolded the numbers of each bar's original rating. If anyone sees anything that I may have missed please let me know.
