Spit/109 sea level speed comparisons in 1.08 beta patch

[pstyle]

Hi crumpp, I've no issue with the math. Frankly I'm not scooled up in the formulae to critique it anyways. My interest is more as a historian, rather than engineer.

Can you advise why the Merlin power assumption is around 990bhp? And, when you use, say the Merlin 3, the auto prop and/or the 100 octanes, how do the graphs look?

Sorry if this creates loads of work....
