Highest volatility period-3 oscillators

All known period-3 oscillators with volatility of at least 0.8. (Currently, however, all included here are seminatural except for the statorless one.)

In describing, analysing and comparing them, it may be useful to reference the stag, a p3 oscillator working in b34zs23-a, whose "antlers" arise frequently in these Life oscillators.
