Gen IV Virtual Torque

Trying to get my head around virtual torque and have been following Kyle over at GoatRope on tuning but had some other questions on adjusting the VT tables if some one could chime in ? I just noticed there are 5-10-20-30 degree torque tables. I have only been adjusting the 0 degree column. So if I wanted to successfully raise VT 20% would I have to multiply and extrapolate all the intake and exhaust angle tables to make it a global 20% increase ?

Have you got variable cams? If not then just the 0 degree row is all you need.
