0.5.10 LIVE BB Sigma Values

Source: Vaexa
Higher sigma = better accuracy. It’s not the sole defining attribute for dispersion, and I’ll refer you to the old thread‘s comment section for an explanation, but a ship with a higher sigma can still have worse accuracy than a ship with lower sigma. In general, though, higher = better.
