100' is too much distance over which to compare rain gauges. If you are going to adjust the Vue to the Stratus gauge, mount them as close together as possible. My Stratus is on the opposite side of a 6x6 post from the VP2 ISS. Both are at the top, tops level with each other to avoid rain shadow. They track very closely, within 0.02" or so in most rain events, and also closely track an 8" standard gauge about 6' away sitting on the ground.
OTOH, the wireless VP2 in the back yard, perhaps 200' away, which I use for systems development, hardly ever matches the other gauges. Both VP2s have been carefully calibrated with a NovaLynx tipping bucket calibrator. I don't know what the console adjustment is for, but IMO, if you're going to calibrate a tipping bucket/tipping spoon gauge, it's best to calibrate the mechanism itself.
