Decimal values in Speed - Hecterra

Talking to a customer, we are testing the hecterra solution for controlling orange, tangerine and lemon plantations.
The problem I am facing is due to the need, as agronomists point out, for speed control of the machines with decimal precision.
Example:
Optimized oversight control should be between 2.5 and 3.5 km / h.
For some functions, the necessary control would be between 3.5 and 4.5 km / h.

Are there any partners who faced similar needs in the hecterra app?
Do developers see any way out to meet this demand?
