5 point total on all categories.
1 point a nail.
Each nail is judged on its own merit.
The nail must meet all of the criteria for the category being judged to earn its point.
1/2 points are allowed when stated.
Convex
The exterior of the nail form should be contoured completely symmetric
The surface of the nail should have no inconsistencies or appear to be uneven on the outer surface.
The judge will examine the nail by looking at it from the front perspective to check to make certain zone 3 is correct and from the back side perspectives to check to make certain zone 2 is correct.
The nail can earn a 1/2 point for each correct zone.
Concave
The interior contour of the free edge must be completely symmetric.
1 point can be earned for each nail.
Arch and Apex
The high point (apex) of the arch should not appear overly apparent.
It should have a subtle and gradual incline that is located consistently in the second zone (see example) of each nail.
The entire arch including the apex, should be not be overly apparent or appear too flat in the second zone.
The arch should not be located too far forward or back in the second zone when looking at the entire nail from a profile perspective.
The nail can earn a 1/2 point for each of these two criteria that are required.
