This could cause channeling. Weigh this against the benefits (basically, none) and you may understand why I recommend against it.
Again, there is benefit to me. If I leave that grind coffee layer on the side of the basket it tends to collect on the side of the dispersion screen at the joint with the screens. The coffee collects there and is not fully removed by the p/f wiggle.
I really do not see how this could disrupt the puck adhesion to the basket. We are talking about a very little suction here. And as I wrote before you would have to be careful to avoid doing it if you didn't want it. I just do it twice to clean the side. No need to flip the basket (I have done that before), no need for side tap (now that will disrupt a seal).
I just saw the Heather video. Just is going against a lot of what is being advocated by different people here. Nonetheless, I just realised that indeed if you overdose, like she does, you do not see the suction occurring as the tamper really does not go deep enough in the basket...

Read Ken's text (I am sure you did already). I have the same reaction to Spanish, Californian or British-Columbia wines. They are so extreme, so excessively woody and charred, so fruity, that although I really enjoy it, I will mostly select and drink Italian (Toscana) or French (Bordeaux) wine. The latter two are by no mean soft and delicate but they offer a more balanced, orchestrated flavour. These are just generalisation used to give an example, there are wonderful wine and coffee to be had anywhere. One just has to find them.
I would welcome anyone's recommendation for Montreal region roasted coffee? I am not a fan of ordering coffee by mail.
