| 这不是不允许,但定级中可能应该有个"5.11a PG" (或"5.11a  R" 如果底下有凶石头)之类的严重程度标度。可惜YDS里没有标准的严重程度等级,各地定自己的。wikipedia已经把Gunks的等级称作YDS的严重等级了,所以大概应该算是标准了: http://en.wikipedia.org/wiki/Gra ... S_protection_rating
 
 * G – Good, solid protection ground up
 * PG – Pretty good, few sections of poor or non-existent placements
 * PG13 – OK protection, falls may be long but will probably not cause serious injury.
 * R – Runout, some protection placements may be very far apart (possibility of broken bones, even when properly protected)
 * X – No protection, extremely dangerous (possibility of death, even when properly protected)
