The different coders agree perfectly (including the situation when they both said dont know)
The different coders are not more than 1 point apart, on the original scale and ratings do not cross the boundary between 1.0 (no problem), and some problem (1.5 and higher) on the original scale
One of the first two coders says dont know, and the other two raters would have received a reliability score of 1, 2, or 3 if they had been the only raters
The coders are more than 1 point apart on the original scale, but the ratings do not cross the dichotomy between 1.0 and more than 1.0 on the original scale
Two coders are more than 1 point apart and their scores are not on one side of the dichotomy mentioned in reliability score 5
One of the two or three raters says dont know, and the second one (if there are only two raters) is assigned a score of 1-5; if there are three raters, the other two do not meet the reliability conditions of reliability score 4 or 6

The different coders agree perfectly (including the situation when they both said dont know)
The different coders are not more than .5 point apart on the original scale (except that the difference between 1.0 and 1.5 is coded as 7 because 1.5 suggests some problem, whereas 1.0 suggests no problem)
