Take a proper size plate, placing a small amount of water, then disc (face down) add just enough water to cover inside surface, heat for 1-1.5 min. remove and lay on flat cool surface. You can take a little or a lot of dome out.
Dome and parting line height characteristics aren't directly proportional to each other. Flattening a disc won't change the parting line height, so it can be assumed that dome doesn't affect disc stability as much as parting line height.
For instance, I have two predators from different runs that have similar domes. One has a much higher parting line height than the other. The high PLH predator files much more overstable than the other.
I'll have to disagree with you on that one. Flattening or increasing the dome can indeed affect the PLH. When I got my FR Axes I tried to give the green one a bit more dome (totally flat, and more understable than the orange moderately domey one). I succeeded, and actually gave it too much dome, it resembled one of the pink ones. I checked the PLH and it was now much higher than the orange ones, and had developed a proper fade (like the pink ones). I then flattened it again, back to totally flat, PLH was lower than the orange one, like it was originally. Then I again added dome, this time I was more careful and added only a bit, now it matched the orange both in dome and PLH.
They aren't directly related and flattening/adding dome won't always do anything to the stability, but anything can happen.
