How do I set the timing windows of OpenITG to match DDR A's?

From what I understand, DDR is timed based on frames, whereas Stepmania/ITG is purely by milliseconds.

There's an OpenITG machine local to me that I want to change to match DDR A's timing windows. It's a little too lenient currently, feels like cheating.

Found a reddit thread that says DDR's windows (no version listed) are:
Marvelous: +/- 16.7 ms (+/- One Frame)
Perfect: +/- 33 ms (+/- Two Frames)
Great: +/- 92 ms (+/- 5.5 Frames)
Good: +/- 142 ms (+/- 8.5 Frames)
Boo: +/- 225 ms (+/- 13.5 Frames)

And ITG's:
Fantastic: +/- 21.5 ms
Excellent: +/- 43 ms
Great: +/- 102 ms
Decent: +/- 135 ms
Way Off: +/- 180 ms

If I set the values to match what's listed above for DDR, is that going to be exactly how it is on DDR A, or do they have a different window for it?

Actually, we believe that DDR A now uses millisecond-based timing instead of frame-based timing, evidenced by how many more MFC's there are now, so actually those timing windows should be accurate to how real DDR plays.

Still, as far as I know those timing windows are accurate.
