The trough pair that hit at lunch was a part of a circle you know 388, 338,220,200,559,599,229,299,339,399,449,499,212,112,313,113,118,188,616,116,099,717,117,900 trough pairs are going to hit in two cycle sometimes 3 when you see one you'll see another soon. 

I decided if i explain something on a board I'm going to post it to the blog so it doesn't get lost
