To set the vertical position is a bit more difficult, the shadow is sliding up and down and simultaneously stretch larger and smaller. Set the base Y position at 35 pixels (from the top) and subtract the sum of ΓÇÿy1ΓÇÖ multiplied by ΓÇö0.3.
Set Property ("/shadow", Y Position) = 35-(y1*-0.3)
The stretching-part is a bit like that too. Set the percentage of the Y-Scale at 180% and subtract the sum of ΓÇÿy1ΓÇÖ divided by 3.
