 Pressure
-    Uses the pressure input of your tablet.
+    Uses the pressure in and out values of your stylus.
+PressureIn
+    Uses only pressure in values of your stylus. You can think of it as a value that can go only up while the stylus touches the tablet. This is best explained with a simple analogy. Say we have a horizontal tube and inside the tube there's a ball that we can push. The ball at the far left means 0% pressure while the ball at the far right of the tube means 100% pressure. If we use a rod to push the ball we move it towards the right, way we move it 30% to the right (30% pressure), we then stop pushing the ball while still keeping the rod inside the tube (stylus still touching the tablet). The ball still remains at the 30% mark even if we're not pushing on it any longer. This is equivalent to PressureIn being fixed at 30% even if we start releasing the pressure on our tablet. PressureIn is a one-way directional pressure input. If we then continue pushing the ball towards the right end (stylus never left the tablet), say we push the ball up to 70% mark (70% pressure) and we pull the rod back, the ball remains at the 70% mark (pressure remains fixed at 70%). So we see PressureIn goes only up as long as the stylus never leaves the tablet surface. It's best to experiment with it to understand how it behaves.
