Essentially, you have done exactly the right thing. Please ensure you
don't use adaptive deceleration, which would explain that.

You might try using the default profile and xset m 1 0. Technically this
is polynomial but flat, ruling out adaptive decel.

If the inaccuracy prevails, it would be helpful if you could be more
descriptive about what's wrong.

Thanks in advance,
