Hi Rob, Thanks for that. I will probably mention that these results could be improved with an increased limit in Cell count. 

With this slightly 'sacrificed' value of Y+ in favour of Ortho Quality, Skewness and Aspect Ratio, I seem to be getting less variance in lift and drag coefficient values as I increase my Mach number from 0.6 to 0.8 in increments of 0.01.

I wonder if this is an expected effect of a lower Y+?

My lift and drag graphs converge perfectly every time but my residuals not so much probably due to the Y+ value.
