Can I match Windows' touchpad acceleration curve to that of my MacBook's trackpad?

Can I match Windows' touchpad acceleration curve to that of my MacBook's
trackpad?

I recently got a Logitech T650 at work for reasons of a RSI nature.
I have a MacBook Air at home, and have used Apple laptops for the last 10+
years.
Windows and OS X's varying pointer acceleration curves never bothered me
before because I used a trackpad on my mac and a mouse on windows... but
using a touchpad on both makes this subtle difference annoying.
There's some options out there to help people who are used to Windows
adjust their Macs, but I'm accustomed to OS X's acceleration curve so I
would rather change Windows.
I'm guessing I can change SmoothMouseXCurve and SmoothMouseYCurve in the
registry, but I can't find any data of what values would correspond to the
third-slowest tracking speed on the Mountain Lion trackpad prefpane.
