This is the case of treating a person for yellow jaundice who just turned out to be a Chinese. As Peter G-W pointed out the speed/Mach for this altitude is rather low. In normal climb or cruise it would be at least .76 which would be closer to 300KTS. The full speed tape runs about 90KTS from top to bottom so this fact is hidden from view. But I gave you the calculations and explanation in the earlier post. Every thing is normal.
