I think you missed a decimal point... 1.8 knots too high, 90 knots too low.

an owner yesterday WHO HAD SAILED THE BOAT, under high wind and low
wind conditions

funny, but you seem to have neglected to mention what wind speed the owner
felt
was "high" for the boat and which was "low". Most feel 18 knots wind is
too
high for a mac and 9 knots is too low.
