This is just an anecdote, but i'll ask anyway. You have the end of wave (v) on 03/05/16, then you have wave (i) on 24/05/16 which is right after that wave (v). Don't you need an a-b-c between? In other words, isn't the end of wave (i) supposed to be its beginning?
@tomg10, hello! you should lead the theory :) this wave (v) is a part of wave of A. then, wave (i), which you mentioned, is a part of wave . so, there's ----, which is wave A, and --, which is in progress (wave B)
