How does B tension affect shifting?
So what does happen when the B-Tension adjustment is too far away from the cog? Essentially, it just slows down your shifting. It will still work, but as the derailleur pushes on the chain from the inside, the shift takes place when the chain picks up the tooth on the next cog.
