2.02 for the sharp (ratio of rear to front)
1.99 for the natural (ratio of rear to front)

Natural wins the speed test by a hair!  But it's neck and neck.

Now, Jim, since you're being so helpful ---

Does the greater mass of the natural key make up for the tiny difference,
by introducing more inertia?

Or, does the leading make up for it? Which key is heavier, and what is the
balance of each?

Maybe I need a nice gram scale and jig, like I saw David Stanwood using in
his class at the convention, to weigh the balance of the key.

If this sort of posting goes on much longer, I may shed a few grams of
ignorance ...
