if you pause the trick mid air, and meausure how tall his is, you can guess that in his grab he is about 4 feet tall. Measure the height where he popped to how he landed and it is about 7-8 body heights, which is 28-32 feet... I would say that from where the cliff starts to where he landed (notice that he did not land directly under cliff, but a good 10-15 feet past the cliff.. he used the cliff to drop approximately 30 feet vertical whilst doing a switch 540.
