Lightroom/ACR: Have negative local clarity work like negative local sharpening

A recent discovery indicates locals are being applied before globals. In the case of negative clarity, a negative local value will *not* be interpreted as an offset to the global clarity, but instead will negatively clarify the region (this is non-reversible by positive clarification). Then that negatively clarified region will be subjected to the full force of the global clarity setting.

I would prefer if local clarity worked the same as local sharpening:

+1 to +100 adds to global clarifying effect. (linearly? -dunno).
-1 to -50 removes global clarifying effect by .5% to 100%, respectively.
-50 to -100 overrides global clarity completely and negatively clarifies instead.

And please make it clear on the local slider and in the documentation, that there are 3 distinct ranges / behaviors - ditto for local sharpening.

Summary: As presently implemented, negative local clarity does *not* reduce global clarity. Insead, it negatively clarifies the region before global clarity is applied, which is different, and in my opinion: not as desirable.

I think the "recent discovery" Rob is referefering to is in this LR forum posting:

So, now that we know adobe has inconsistent behavior between local and global changes, if adobe makes it consistent, do we not also need a PV2012-2? Otherwise changing the behavior will change all your existing 2012 processing... Well I suppose before this happens it will be 2014 or later.

Would definitely be a new PV.

Although in the case of clarity, much less so than for sharpening (when same change was made), I doubt there would be many images worsened by such a change. Still, there would be some subtle differences on some images...
