Just a thought from my experience and opinion: Try not to limit yourself to one particular view of teaching and open your mind beyond the constraints of your schooling. Store what you've learned to your skill toolbox and make a judgement for every given situation (every turn). Then you can exploit what you've learned to find what works best to inspire confidence in your riding. Then you become your own coach.
I have four bikes that behave completely differently when it comes to throttle control. Between riding my 17' S1KRR, 14' Monster 796, 15' Panigale 899, and 94' ninja EX500 (track only) they all require different timing and "finesse" for all varying types of turns. The ducs are "L-twins" which makes them even more touchy than v-twins. The panigale is even MORE difficult to ride smoothly than the monster as ducati switched to drive-by-wire and their throttle control is "touchy" to say the least. Both L-twins require significantly more finesse with throttle inputs for a smooth ride and more "attention" than my BMW and Kawasaki. They also require you to stay in an appropriate power band which makes inputs much smoother and less choppy.
That being said, you've already mentioned applying throttle early on which can settle the bike and make your throttle roll on smoother. This partially comes from loading the suspension and chain (feel it out and experiment). However, rolling on too early prevents your ability to load the front tire into the turn (if you trail break), can widen your line, and you often have to lean more than you normally would to make the turn (unless you tighten it with the rear brake). This technique may inspire confidence for some turns but definitely not for all. If you can afford the lean angle, go for it but don't make it a habit as it reduces available options on the street.
For the monster on the street, I typically make an effort to be in the appropriate RPMs and very finely roll-on until I feel everything get tight. Then I maintain that until I roll on continuously throughout remainder of the turn-typically as soon as I know I'll make the exit. Remember than when you lean the bike, your rpms will increase as well and if you're in a gear too low you can run out of revs quickly in a low revving v-twin engine.
The panigale 899 is notorious for its touchy throttle and engine braking. For this bike I use even more finesse with similar technique as the monster above and it makes me a better rider on the monster.
The most important thing you can do is remain relaxed in your hands. It's difficult to make 1mm throttle inputs when you have a death grip or you are weighting your arms. Be conscious of your body position and what you are doing with your legs. Perfecting your riding on a difficult bike with a touchy throttle will make riding a smoother bike that much easier-trust me. Hope this helps!
