What does the B-tension adjustment bolt on Shimano gears do?

This bolt governs the distance between the rear gear's top jockey wheel and the rear cogs. Basically you want the jockey wheel to be as close as possible to the cogs, but not so close that it rubs. The biggest cog is the test. If the jockey wheel doesn't touch this, it should be okay in any gear.
