Force mastery, Force augmentation and raw power
Although there's obviously a correlation, there does seem to be a difference in combatants' ranking with respect to their telekinesis/etc., and their ability to augment their physicals/enhance their precog in a duel. For example, Dooku has better telekinesis feats than Anakin, but Anakin is so powerful that he can destroy Tyranus in a duel when he really tries. I doubt this is because of Anakin's muscles - Dooku can easily beat Grievous. So why the distinction?
My theory is that Force augmentation more reflects your raw power, which correlates with potential more than your refined mastery of telekinesis and other techniques. That's why Anakin would stand a much better chance against Sidious in a duel than a Force fight, even though the Force is the primary determinant in both.
What does KMC think?
EDIT: also, how would this tie into your Force defenses?
