I wanted to share with the group that after a year and 130 hours, I have some interference issues that have manifested themselves. I first noticed that the sticks were a lot freer when I was solo and wearing a chute. My chute is a seatpack and basically all my weight is supported by the back of the seat. So under the seat pan, I found this evidence that the stick mount was scraping the seat pan:

As I was working my fix, I also noticed a scrape on the elevator pushrod between the stick mount and the idler:

I fabricated a hat section with the angle that I expect the seat pan to follow:

I rested it in place, put the seat pan on, and evaluated. It seems good and I am going to rivet it in.

So I was super meticulous about ensuring no interference before, but with all the seat cycles and maybe Gs it changed over time. I may make a couple of similar hat sections to go on the sides.
To reiterate one of my philosophies - how much interference is allowable? NONE!
Stay tuned...
