Pointer Acceleration

After quite some testing of the new predictable pointer code introduced
with version 1.6 I have a question.

My mouse is a Logitech MX 518 set to 1600 dpi via lomoco and using HAL.

With the old pointer acceleration code (now lightweight scheme) my mouse
cursor behaves perfectly with the following command:

xset m 16/100 1

Even for far and fast mouse movement I can accurately hit small objects.

However, I'm not able to reproduce that accuracy with the new code. I
tried the Simple Profile (4) with a ConstantDeceleration of 6.25 and
xset m 1 1, but it just doesn't feel right; neither does polynomial

Is there a way to exactly reproduce this old behavior with the new code?
I don't like to rely on a scheme that is kinda considered obsolete.
