NoteStatic radial is printed as 3,360, which is higher than every size up to 8.000 in. and out of sequence with its neighbours. Interpolating 5.000 in. (2,158) and 6.000 in. (2,567) gives 2,362, and scaling from the Type A value for the same size gives 2,357 - a single wrong leading digit. The corrected value 2,360 is shown.
