I definitely commend people who keep up with the dev posts, it eliminates questions like "is cure potency and waltz potency the same thing" however we did actual research on the potency received effects that Corsairs can also grant. It (well, cure potency, waltzes aren't affected by weather that I know of) multiplies (not adds) to weather effects too unlike the Twilight Cape which adds to weather effects. This means you get an even bigger bonus then if it just counted as a boosted weather effect bonus.
