You are not being annoying Mr. Thomas. I applaud you sticking with it and curiosity to know more. You're correct through points 1 and 2.

Briefly about point 3, it's possible to retain an Artist Performance File audio, restore it as a RealTrack for editing and not lose any material. Meaning a APF can revert back to a RealTrack without regenerating new material and losing that well designed solo. BIAB provides the flexibility to change parts of the performance and retain what you want to save.

The attached screenshots show the WAV form as it appears in each step of converting and restoring the track from a RT to a APF and restored back to a RT.
I've reached the maximum attachments with this post so I will add a screen shot of the original and restored track side by side in a separate post.
