I noticed that it doesn't say what damage is inflicted by falling. There is the rule that for each 10KPH (rounded down) in a vehicle crash you take a d10.

I get the following for each 10 feet
10 27.8Kph 2d10
20 39.3Kph 3d10
30 48.2Kph 4d10
40 55.7Kph 5d10
50 62.2Kph 6d10
60 68.2Kph 6d10
70 73.6Kph 7d10
80 78.7Kph 7d10
90 83.5Kph 8d10
100 88.0Kph 8d10
so starting with 2d10 @ 10ft and adding 1d10 per additional 10 feet
