Im still surprised by the difference having a pullman tamper fitted to the synesso basket made. I firmly believe that helped a lot with reducing the flow around the edges.
Also my evening shots are always better because the machine has been on a little longer, and from a warmer ambient temp. Plus, not being half alseep in the mornings doesnt help (tho sometimes, oddly, it does!)
I had the exact same tamper as you (well, it looks identical...aluminium?) and it was a millimeter too small for my double basket
I was suffering similar issues as you, so hunted for one that fit my basket with barely any wiggle room, and noticed an instant and definite improvement.
Another thing i learned was to take care when tamping- keep the action as vertical as possible. Its hard to tell from the video angle but it looks like you leaned forward a little when tamping.
I also dont know about the fill-level-rest-fill-level-tamp method..never worked for me, I just fill-level-tamp.
Id be interested to know if you do change tamper whether your grind becomes coarser. With a new tamper, i realized i had previously been grinding too fine, to compensate for uneven puck density around the edges.
Good luck.
I had a good double today with a simplified dosing method (no knocking down on the bench, just resting the tamper on it) - back to a method I used to use.
Looks like you are leaking from around the top of the portafilter in that last one.
How do the single shots look with the double spouts, or the double shot with the single spout? Cant really compare the pours without taking this variable out.
The double shot looked fine to me.
Have you tried grinding finer, not collapsing, tamping and then refilling, collapsing, tamping but instead just filling once?
I fill once, round off the top with my finger to a dome tamp lightly and thats it.
I dunno mate. The pour didnt seem too bad to me, I must say.
Those holes in the top of the puck could be the start of channelling, hard to say. If you are getting channelling here, itll be down to the Tamper most likely - Too much space between the sides of the Filter Basket and the O.D. of the Tamper Base...
You could probably finesse your Dose/Distribution routine somewhat in order to ensure uniformity and consistency (basically, make it simpler and less likely to introduce anomalies).
Once you can grab a bottomless Group Handle, it will be a lot easier to see whats going on of course - Perhaps you can borrow one...
Video of a double from last week. Fresh beans (<24h post roast, so this probably looks better than many of them), my usual dosing technique. The puck picture above is from this shot. Ignore the commentary from my daughter who decided this was a good time to pinch me on the bum.
Ive played with dose, grind, and tamp and it either pours watery or gushes. Ill try to get a vid of a single for comparison some time, but the single seems much more forgiving and pours much richer/thicker.

yep. curved edge does the trick. guy from LM has explained to me. I think LM delievers such curved baskets.
hard to translate from italian,but it works!!! :
And I think LM probably have the very worst baskets Ive ever used or seen come with a machine. :P

when I level I use a curved edge (scott callaghans dosing tools) to take out an exact amount and with doubles I use a straight edge.
Phil are you reading this?
Trouble with those dosing tools is that they dont leave in an exact amount. If you have ground, dosed and settled at all differently, then you will be left with a different amount in the basket every time.
I met a guy called Phil who came up with the solution, but I cant say more because I think he is still obtaining patents.
But what if you do dose and tamp reasonably consistently? Then your singles are reproducible. These dosing tools have helped me achieve this consistency.
