Why don´t these figures match up?

So I'm getting the feeling that the speed gauges in CloD are a mess. It seems that they show an incorrect (too slow) speed.
15% too slow for the Spit and 5% too slow for the 109.

If you think further and considering the numbers MusseMus brought up a few posts earlier, the FM of the Spitfire actualy could be 15% faster than the gauge indicates and the Me109 would be arround 5% faster.
Maybe it's "just" an issue of incorrect display of gauges rather than incorrect FM Should be very easy to fix I suppose...

Something to think about:

I can't draw a definite conclusion but between testing that may not be accurate, considerations of the 'standard day' and possible differences in the way gauges are fed with data there's a lot open to debate. After the patch I'll test a Spitfire and a 109 to see how they pan out. I'll also update this:

to look at Z_TAS as well as TAS calculated from IAS gauge to see how they compare. You may like to use it for testing then. We could be in for some surprises.
