GUI value logic or calculation

Hello All.

A query:
Does the GUI value and the respective value is having any logic or calculation or it is internally calulated?

For example, for t310…

For t310, I suggest you use either 500msec or 1000msec.

Yes that’s OK, thanks.

But actually I want to know any “logic” behind the GUI and the value specified.
As not looking like incremental in any fixed step size.

Check 3gpp 36.331 for GUI values and Real values.

GUI is just a number software uses to interpret the value.
There is no formula or logic behind it.
This is just programming practice vendor used.
