Table 1 Suggested interpretation of RUI values
Relative unlevelness index (RUI) | Visual appearance of levelness |
|---|---|
< 0.2 | Excellent levelness (unlevelness not detectable) |
0.2–0.49 | Good levelness (noticeable unlevelness under close examination) |
0.5–1.0 | Poor levelness (apparent unlevelness) |
> 1.0 | Bad levelness (conspicuous unlevelness) |
