The cold PF will "steal" heat away from the group and can lower your overall brew temp. So attempt to keep your PF loaded into the group when not in use and see how that impacts your results.
This ^^^ is for real.

It's one of the tricks we do on our Pavoni levers to squeeze out an extra shot before it starts becoming too hot, in case we want to do more than two. Putting in a cold PF, refrigerated or even frozen, really sucks down the temp. This is good for us Pavoni users, but probably bad for the OP.

I don't seem to have anything thin and wiry at hand (not even paperclips, which others have mentioned as good substitutes), but I'm hoping I can find a dissection needle at Walmart, as I dislike ordering small things like that online (but may have to in this case).
The toothpick should work fine. After WDT, try tapping the PF gently on the countertop . The grounds should level out nicely, ready to tamp.
