If you have 3 soul after the second wave, you can do the optimal damage rotation for Traitor Lord pretty reliably without scream skipping. By itself this saves 0.3 because of no freeze frames, but if you are 1HP after frogs you save an additional 2 seconds because you don't have to heal and then get soul.
Go for the double on the first wave and then go for double double on the second wave. For every double you miss, get 3 nail hits and fireball so you still end with a cast. The only meaningful downside is if Traitor Lord does three grounded dashes in a row, it's really hard and maybe not possible to get enough soul hits to do the last double, so you'll have to get 3 extra nail hits and fireball, but this is still faster than healing.
