I have been wondering this for a while. Even in the previous faq it reads like you are comparing the start Ht and the end Ht. So what do you do if say there is a 3 Ht wall and you want to go from one side to the other? If the ground is the same Ht on both side of the wall, do you just ignore it and do your full Wk through it? Thanks!
