Difference in clubhead speed between FSX2020 and GC2 display

[ElPrimero]

Hi,

I realised that the clubheadspeed the GC2 shows on its display and the speed FSX2020 shows often differ. I asumed a rounding problem firstly because most of the time the difference is 1 mph but now I see 2 mph differences as well.

How can this happen?
