I don't do the butterfly and I don't do the redirection point (just leave a little loop of rope hanging there), so for me it's only 4 cloves. If you get the length of any arm wrong it's super quick to adjust since you can just fiddle with the clove. Also breaking down the cordelette and folding it up neatly takes a little bit of time.
Other benefits: If a piece fails there is zero to minimal extension, you need to tie overhand limiter knots in each arm of a cordellete to approximate this, or else accept some possible extension. It's also much easier to keep safer angles between each arm than it is with a cordellete.
My other main reason for occasionally using this method is my partners hate using cordelletes, so I've basically stopped using them too.
Edit to address leading in blocks and swapping leads: Yes, those are some fair points. I never said this is the best method for every situation. Clearly you are very emotionally attached to your current method being best. My point in posting the pic was to explain why I asked about the safety of the tie-in loop. Rich Goldstone has a pretty strong reputation for safety, and he indicated that he often uses the tie-in loop rather than using the butterfly knot. He didn't indicate what he uses for a tie-in knot though.
