It's an illusion.

The PPS is where it is to serve the masters of the market, the MMs.

And it seems they want to accumulate here, so the PPS will be increased and decreased to allow them to shake as many shares as they can.

in my opinion. there is a stealth accumulation going on, and the PPS level is there only to serve that.
