What about DDR timing windows on an ITG cabinet?

The ITG dedicab I play ITG at has a bunch of DDR songs and mods for making the timing windows smaller.
So if I play a DDR official chart on that machine, and use a mod that sets the timing windows to be close to the DDR timing windows, would the score be legit to post to the score tracker here?
Using the info from http://www.stepmania.com/wiki/Stepmania.ini 77.5% timing would be a perfect fit for the marv and perf windows, and 80% is the closest mod currently on the machine.
I'm pretty sure I can also get a friend to yell stupid shit every 5 seconds since the machine doesn't have an announcer.

Not allowed, strictly only DDR running on KONAMI machines only; as things like this are hard to prove in case of disputes.

It you're drawing that hard of a line, then why don't you force all scores to have proof?

---

Any score with proof automatically over takes any score without proof in the rankings so there really isn't an issue here.

Okay, I guess that's a good way to run it, rather than deal with all the people arguing over it.

Besides, the method for timing windows is completely different from ITG and DDR.

DDR measures windows in frames. ITG measures them in milliseconds. You can approximate the DDR timing windows on ITG but they will never be exact due to the different methods being used to determine the windows.
