They should probably explain the process in an operating manual but I looked at their website and they have no download. To calculate the weight from the polar chart, use the standard formula of ((hp/10) + 30))* IPS. Multiply that by the distance from crank center to sensor/distance from crank center to the location of the weight. Tradition is that the polar charts give the location of the heavy spot so you need the add the weight 180 degs. Standing in front of the prop, the weight location is measured CCW from the sensor tape location.

In the process, you learn exactly how to best use the dynavibe and learn how I do split weight calculations. Jim
Are you using my wife's spreadsheet? How's it working for you?
