If I plug MC 10 knots into my speed to fly spreadsheet for my LAK-17A
18M dry (which is likely to have a higher STF than your IIC for the
same MC setting), I get 148 mph (130 knots) for 0 airmass movement.
In order to get an STF of 200 mph, I would need to be in 10 knots of
sink.

Which is not at all impossible in the mountains!

He didn't say he was in 10 knots of sink. The implication was that STF called
for a "cruise" speed of 200+ MPH. It does not.
