Again, I’m not trying to say these words have a single defined meaning. I’m saying that SpaceX’s reusable rockets are in a different category compared to SRBs. Call those reusable and refurbishable if you like, or call them anything else. I just use the reusable refurbishable terminology because that’s what everyday astronaut uses.
Do you know the turn around time on an srb? I couldn’t find it in your doc or in the wiki.
