My own, possibly wrong, but strongly held nonetheless, opinion on all such exercises.....don't waste your time.
There are so many pedagogical exercises these days. They're great for padding out courses and selling books, but IMO they distract from the greater goal.
It's like the old "finger pointing at the moon" metaphor. You get so caught up on all the minutae, that you forget where you actually want to go.
Unless you have an infinite number of hours to practice each day, your time is better spent in other areas. I reckon every beginner and intermediate level player, reaches the point where they realise that playing jazz takes a fair level of technique and familiarity with the horn. I'm still getting to grips with the Bebop stuff.
It's easy, to say to yourself "I need to improve my technique and speed, to play Jazz."
From that realization, you can either go out and purchase a whole bunch of technique books and spend years getting your technique up to snuff and then hope that that technique translates into being able to play Jazz.
Or you can just shed Bebop Heads and solos in all 12 keys and you'll find that this brings your technique along. Not only that, but you're actually playing jazz and learning vocabulary and repertoire at the same time.
Don't waste your time on all the ancilliary stuff, unless you have a very specific problem that needs addressing. Just remember the 80-20 rule.
80% of everything you practice will contribute to 20% of your playing ability.
The other 20% of your practice will account for 80% of your playing ability.
I, and just about every player I've ever spoken to, have wasted so much time on all the stuff that doesn't really get you where you want to go, until you finally have some old guy pull you aside and say "forget all that nonsense....learn tunes in all keys, transcribe the players you like, play as often as you can, and the rest of it will take care of itself."
All the ancilliary pedagogical stuff is useful if you're trying to sell a 4 year college program, but for most of us, there are more immediate and basic concerns.
Put another way...."when you're up to your sphincter in alligators, you don't worry about the mosquitoes."
