Re-chart it to show from the very beginning point in time/level what the rest of the mess is being compared to, because your wave is not correctly drawn and you allude to some earlier "something" which is not clearly labeled. Please take some time to chart everything important and exclude everything else.
If your point is valuable enough to post, then it should be worthy of your posting it so no one can misunderstand. And so far, apparently no one can understand what you have posted. Part of the problem is you have not drawn the PA wave correctly. I suggest you restart by correcting that error.
