Greg,
It's a nice chart.
If you don't mind a couple of suggestions ...
You don't need the 7 at the end of ∆ chords, as the 7 is understood. Leaving off the 7 makes a less cluttered chart.
I see that you're trying to get the syncopation by writing chords after the first beat of the measure. Unfortunately, that doesn't work for playback, as the whole measure plays the chord. Many of us wish that iReal pro could be divided into eight eighths instead just odd eighths.
I prefer, as an alternative to writing the number of repeats under the last solo measure, to label the head the Intro and the solos the A section, and use the Repeats function at the bottom of the window. That way I can keep track of the number choruses played by the indicator at the upper right.
Cheers,
Jer
