Formula to calculate weights when dynamic balancing prop ?

[petersb]

I have access to the basic DynaVibe prop balancer.

I understand the technique used by the pro's is to check the uncorrected propeller balance then apply a random weight so the computer can see the result and then use this to calculate the correct weight and position.

The DynaVibe unit we have does not have this computing function.

Does anyone have a spreed sheet, iphone app etc that can make this calculation.

We are currently using the basic (Engine Horsepower/10) + 30 formula.
