Here is another one that just shows a single shot with coffee, showing the initial spike, subsequent drop, then slow decline. But, the pressures here are generally above what the blind basket shows after a few shots on the first video.
Also, here is a video made by someone else showing very similar behavior to mine (found on a different forum):
