"62-77" is slightly somewhat confusing- this should . From a casual reading it appears to mean it is not that 9 floors are possible with 62skill, but it actually means that the skill boundary lies somewhere between 62 and 77 so it is not possible with 77. If 62 (if this is not the case, please move the 62 value where it belongs). Strongly recommend using "62 < x < 77" I cannot think of a better way to avoid further confusionexpress this though.
