Gcode Speed higher than Cura Settings?

Can anybody help me understand why the speed in the Gcode exceeds any of the speed settings I enter in the slicer?

I've attached my profile and the Gcode.

 

The settings have a maximum speed of 250mm/s which is F15000

 

However the Gcode goes to F17341 which is 289mm/s

 

It seems related to multiple settings.
At 0.2mm layer the speed does not exceed F1500
At 0.28mm layer it goes to F17341
Then changing seam settings from 'sharpest corner - smart hiding' to 'user set back - hiding', it goes up again. Now F17442

    Hey @ssashton,

     

    Thanks for your report 👍

    It baffled me a bit and reminded me a bit of this feature request on our github.

     

    I asked around a bit and it might be related to the setting Flow Equalization Ration.
    You can read more about the setting here.

    Can you change this setting either to 0 or 100 percent to see if the speed matches your expectations better?
    Thank you 🙏

    Thank you, that's a superb answer and seems to be 100% correct!
