There is simply no other reasonable explanation for these insane algo tweaks and the way/speed/frequency they are being implemented of late

Well there is, they are not happy with results and trying to correct it, but failing probably as the underlying Panada is not correct. Have a funny feeling...lots more changes to come and these may be on the fly rather than data pushes.
