Why don´t these figures match up?

So I did this test in QMB (no wind, 100 meters hight):

Time: 3 minutes (0.05h)
Speed: 250 Km/h IAS (with this low alt and speed TAS/IAS shouldn´t make a big difference I guess)

So after the math is done (250km/h x 0.05h) the flown distance should be exactely 12.5 Km

I did the test several times with several planes and everytime the actual flown distance is 14,5 Km (that indicates a speed of somewhere around 285 Km/h).

Does anyone know where I did the mistake or is just some of the tools in the game broken (Speed gauge or distance meassure on the map)?

Thanks for help!

The reason I ask is because in a test made in another thread (http://forum.1cpublishing.eu/showthread.php?t=34115) the results shows that the Spitfire in COD is roughly 14% slower than real life.

Since your figures show a 14% speed gauge error, it's tempting to suspect it's accually the speed gauge in the spit thats porked, not necessarily the FM

But it might just be a coincidence

Also it's not an FM issue because even with a completely wrong FM (say if you do the calculation with the "FM" of a juggernaut, you should get the expected values).

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...

Yes I found gauge is in error too, just wondering if one of you started a bug tracker that I could cast my vote.
