I found my notes from the IAO tech conference. I typed them up to post here at AO for reference, but would ask that they be reviewed for accuracy first. Keep in mind that these are not installation instructions - just notes and general level-10 trivia I thought important enough to write down during Tom's lecture.
If there are no errors I'll post them to the Level 10 thread.
Thanks,

1. Pull trigger nothing happens = to much oring friction.
2. vent hole size = 22/1000s of inch
3. Shims should be used when leaking or bolt sticking only.
4. 1.5/1000s = difference in each carrier size.
5. Shims move oring closer to vent hole.
6. To choose correct carrier slide onto bolt stem, it shouldn't fall off, but also shouldn't stick.
7. !Use largest oring size that does not leak.
8. When installing DO NOT oil carrier oring, it will cover up any small eaks which will develop when oil dries.
9. Best carrier oring will feel like it's not there when sliding bolt back and forth in power tube.
10. Step down carrier size 1/2 size at a time.
11. Shims = to few will cause bolt stick, to many will cause leaking down barrel.
12. Steps to tuning:
- Nothing when pulling trigger = turn up velocity
- Bang, hiss - turn up more
- Shoots reliably, chrono
- if velocity to low continue to turn up
- If velocity to high change/trim/adjust main spring
13. Level 10 produces a 10-15% reduction in efficiency.
If there are no errors I'll post them to the Level 10 thread.
