Steve,
When you have adjusted pressure on your wheel.It is that certain pressure you just adjusted.When you take a hold of the your panels edges, and press the edges towards floor...you increase the pressure on contact point, cause you get a leverage of the sheet..as you wheel..Think what happens when you put a plastic wrap on top of a ball shape object, and pull the plastic wrap down, the ball wants to come through the plastic wrap..on metal it canīt do that, but the sheet stretches more..via the more pressure applied...
And yes more pressure, faster stretching and faster shape...
This is how I see it...someone can correct, if I am thinking this wrong..
