inverse impulse response - multiple (like 1000) bad exits - detail A

just a zoomed in graph of an area of interest, so I could verify that the window size was the same as (close enough) as what I asked for. The important point being that the window is always exactly around the frequency step point.

Now we already know that the frequency step points are aHWP thing, so this data supports the argument that HWP is doing this stuff on its own.
