Is this used and is it useful? I haven't seen anyone with a rating volatility other than 0.05 or 0.06.

Basically, lichess only uses .06 and .05. .06 means your unpredictable, and your rating can increase more quickly. .05 means your rating is less predictable, so huge swings happen less frequently.
