I don't think he does that, because that would mean he doesn't have a clear enough idea of what needs to be done or that he doesn't have enough technical skills to set up a scene.
There was one important addition that sparked some debate (it's not something that ever bothered me
), but he's not going to have fun rendering to just say to himself 'I made 1400 renderings to keep only 800' .
Even though he doesn't write much on this feed, he does read the posts (when he sees my name he goes to the next message
) And I think that would have already made him react on his side, not to make this mistake.
It can happen to him to redo the same rendering several times because there is something to adjust or that does not match the narration. That seems logical (he has already explained that)
