the regular programs are assuming the spoke holes are all centered
so just alittle more subtraction from hub measurement between the flanges to compensate for spoke hole offset
OR
just use my boy ROCKX program
he is a mad scientist and made the best program for spoke length
its shows u all spoke lengths on bottom for radial(0), 1x, 2x, 3x, 4x
and the spoke pattern program is cool too
just click drivetrain and hub
then pick them on the left tab
