I know what chainline is, thanks. And biasing chainline by up to 3mm on a modern multispeed drivetrain, you say is equivalent to running in one gear all the time?
I guess if that's a pearl of wisdom, I'm a swine...
I'd say that depends entirely on which side of the cassette you hang out on most. Or even just how often you use the smallest cog.
As you correctly noted - those were emphasis - with LABELS and KEY TERMS. And they weren't random.
Short answer to questions is "yes". Because you are taking incremental increase in friction, noise and wear and instead of making an effort to distribute it evenly across both sides of the cogset - you instead bias it more to one half increasing the rate of wear on that half and reducing the rate on the other. As I said earlier, might as well ride 1-3 cogs all the time.
As I stated earlier, if playing loose with the chainline is your cup of tea...that's fine. But in a customer situation, I don't do that by default. My default is to go with a spec backed by a reason first and save the personal "just wing it and make it work" stuff only when a customer pushes back and insists.
It keeps people in the bicycle business out of trouble.
