Predicted Meter while Editing?

Okay, in stepmania, when you edit a song, there is a predicted meter. And some songs are only 9s like Speedcore sunday, and only 1 that i can think of is a 10.05 or something, which was Vertex^2, but Speedcore sunday is the hardest song I have ever played, never passed, yet I have passed Vertex^2 a LOT, does anyone know the "formula" for the predicted meter. Because I also did a test to see if crosses were detected, I made 3 stepcharts for the same song (100 steps every stepchart, same song, just different difficulties) with the same pattern, no crosses, then a different pattern, no crosses, then a different pattern, many crosses, and the same and different ones without crosses got a 1.651050 and the one with crosses got like a 2.5 something. But does anyone know what else effects it? Because also, I made an edit of Monolith, and it was a 9.767... footer (predicted) then I made a LONG stream of sixteenths with a lot of crosses until the end and then the predicted meter was an 8.87 footer or something, does anyone know why this happens?

Thats a good point. Songs with strange beats (triplets and such, purple notes on ITG) with little spacing between them seem to have a high meter. Determinator and Sweet World have pretty high meters in comparison to others. Double taps also sent my meter higher. No idea why, id like to know too, but the Predicted meter is so off that i dont trust it anyway.

yeah, but then i did the same thing on Summer, and it was the same all 3 times, i never use the meter though, I am just trying to make a song that it actually says 15, thats POSSIBLE. I just think that the more complicated the streams are (Vertex2) then the higher the meter. Also, step jump step jump eighth/16ths so on notes usually do a lot, i think the Indulgence predicted meter was actually higher than Vertex2, but I have to check that again.

The Predicted Meter value is calculated by the amount of steps, stream length/density, etc. It does not look for step patterns, which are sometimes responsible for higher difficulty ratings. All ratings in the DDR/ITG series are decided by humans for this reason.

What you need to do is get an idea of what constitutes all the difficulty ratings, and use your best judgment.

Then how come when I make a song with straight 16/32nds throughout the whole song, the meter will be lower than songs like Summer, Indulgence, and Vertex2. It also sometimes puts the meter DOWN in a song with complicated steps and streams. Speedcore Sunday has I think 2000 or more steps in it, and its meter was LESS than Indulgence which has less than 1000. So I just want some kind of explanation for that.

I think it overthinks speed changes. Stepmania gives Supercalifragilisticexpialidocious something like a 9.5 on Maniac. (I guess the stars were right...

)

The amount of chaos in a song (# of 12th notes and beyond) has an unusually high impact on predicted meters. Had the songs' bpms been halved, their predicted meters would've been higher. Even Witch Doctor has a higher predicted meter than some tough 10 footers from DDR. Stepmania 4.0 should make chaos have a much smaller impact on the meter (or better, add a tiny bit of chaos for each 8th note, just as it is in DDR).
