Channeling - a cure for

It's perhaps premature to declare victory, but here goes. After months of trying all manner of approaches, including a triple basket, I seem to have found an approach that has eliminated channeling - no doubt, I'll have a sprayed counter tomorrow morning.
I put 19g of coffee into a double basket. I tap the basket several times on a rubber mat. until the coffee has settled down, followed by more tapping on the side of the PF with my tamper. Then, I nutate (learned that word here - the motion of a spinning coin before it lands flat) first with a very light weight, large nutation(?), but increasing to - guessing 20 pounds and a much smaller nutation, ending with my tamper flat - just like a coin. Finally, I tamp with 30 pounds of pressure and spin the tamper about 1/4 turn.
I'm getting very good, consistent shots, with no channeling. But as with science, this result needs to be reproduced by others for verification. I'm all ears.
