On my first default-lives run of PCB normal, during the random spam in the sixth stage before midboss Youmu, I decided to suicide to auto-collect point items for the next life.... Either way during the spam I unfocused, moved in a triangle shape to get myself hit, and.... survived by pure luck. I then focused and dodged the rest and still got an extra life out of all that :V
I just did some tests-- the stage gives 136 point items if you remain at full power and collect everything until Youmu. By simply dodging the pattern (or dodging followed by a "natural" death after shooting most/all the enemies), I gained ~100-125 from the dialogue auto-collect, while a suicide resulted in a gain of ~67-110 depending on how many enemies were shot before reaching full power again (or escaped during the death).
I forgot about the auto-collect when Youmu arrives. If I didn't I would've tried to stay alive :V
