Mike --
As you compare the raw Plotter charts with the PowerDial and Expo/Dev some slight differences can be expected due to some rounding in the calculations and the point-to-point plotting of the chart lines. But these differences should be trivial; if they're significant it's possible that you're using different ES values in the Plotter and PowerDial.
The calculations in these BTZS aids are based on the equation:
G-bar = ES/SBR
If your results are inconsistent with this equation there's obviously something wrong; tell us more specifically what you're doing and we'll try to find the cause.
