I didn't get a chance to read everything in this thread but I wanted to say this:
Good throttle control also helps with maintaining a predictable line. Contrary to what a lot of people think, if you follow Keith Code’s throttle control rule number one, "once the gas is cracked on it is rolled smoothly, evenly and consistently throughout the remainder of the turn," then you will have a predictable, consistent and smooth line through a corner. Rolling on the gas does not make the bike run wide. The bike will only run wide if you apply the gas too much, too early in a corner or before the bike is fully turned.
The other important thing to note is that you do not need to "Hold" the bike on its line or continue to steer the bike throughout the entire corner. You countersteer the bike into the turn and provided you have good throttle control you can release pressure on that inside bar. You steer into the turn and you steer out of the turn but during the corner you can release pressure on the handlebar. Rolling on the throttle will hold the bike at the arc that you set it on. The bike will maintain that same line until you steer out of it.
