How to oto end breath samples?

[kite]

I recorded a CV voicebank and decided to also record some end breath notes, but I'm not exactly sure how to oto them. I think you're supposed to put the consonant (pink line) as a negative value but again, I'm not too sure

Overlap: Set this to a reasonable value for smooth crossfade, like 80
Offset: Move this so the area between offset and overlap has a stable consistent vowel. It should not be fading out yet.
Preutterance: Put this at the end of the vowel and before the breath. This should be 2x overlap or more. You might need to move the offset a bit more to the left.
Fixed region (pink): This should be covering everything until the end of the breath
Cutoff: Put it just after the fixed region, so there's still an empty white gap. There should be no sound in the white area. The white area needs to exist to prevent errors on longer notes.
