As already stated in a comment A YEAR AGO!,

...editing the phrases or how RB interprets the music, STILL isn't possible.
So, once RB makes a wrong decision , you get this kind of analysis:


Really Pioneer? Does this even remotely seem realistic to you???
Next to that, even on clean house with a bass four to the floor, the software isn't capable of finding the first beat and placing the intro section there.
Or it does the latter, but then decides to place the first beat on the second, etc etc...




And yes, I tried several analysis settings.
It just DOESN'T WORK!
Please Pioneer, get yourself some decent developers to fix this.
Having bugs like this for over a year is just unacceptable, for any brand.
