That's not a basis of Gearing Commander being inaccurate. The 600 would do 230mph in 6th at the redline... if it had the power to do so

The purpose is to show the gearing ratios and related speeds, not to debate the finer points of whether these speeds are possible or in what time they would be achieved

I've relatively certain I had mine quite close to the red line about 11k ish) , at about an indicated 150?

I would imagine variations in the rolling diameter of the wheels and tyres will be the major factor there?
