That is the maximum value expected. That seems high to me.
The maximum value should be high enough to destroy an airframe. It would be worth investigating research into cumulonimbus clouds, downbursts, etc., but I don't think 100 ft/sec is out of line. Unless you want to make the 0-1 turbulence value non-linear, anything about about .1 should be very unpleasant to fly in. I did stumble into a small, developing storm cloud once in my Warrior. Fortunately, the up- and downdrafts had smooth enough transitions not to cause damage, but they pegged my VSI in both directions, threw me back and forth into uncommanded 60-degree banks, and we gained and lost a couple of thousand feet in seconds. It's almost impossible to believe the power stored in even a small storm cloud until you've seen it.
