Now we're getting carried away. The word "minimal" is pretty vague. It's an opinion, right? How do I form my opinion? Decades ago, when I first started designing suspension, I did a series of tests to determine an "acceptable" rate of chain growth. One that had a minimal (to me) amount of pedal kickback. I've ridden the worst and the best. I decided on a "minimal" value, and it's been pretty good to me over the years. If you concentrate and are a perceptive test rider, you can make yourself aware of it. But when you ride the bike the way you want, it's a non-issue.You can say that "The chaingrowth on this design is actually pretty minimal", but that's another lie and you don't want to post the real data because then everyone would see that you are not telling the truth.
Again, I don't post a chain growth number because it is meaningless to me, and really, the feel of the bike, therefore to every other rider. I am trying my best to not overload the customer with meaningless marketing jargon that can't be proven, i.e., my AS/LR/WP/chaingrowth/dick is better than yours. I am showing meaningful RESULTS to my marketing claims, hopefully in a way that people can identify with, rather than arcane specifications.
