Hi, since you seem to have well documented data and good performance,
I'm curious about:

How you determine when the chain is worn out.
Which chains you use.
What conditions you ride in (wet, dry, dusty?).
Type of cogs/rings and how long they last.

There are a lot of opinions on this subject, but objective long-term
information is pretty rare...
