I think this is a good question in terms of understanding the detailing process 'scientifically'. What are the pros & cons of working by hand vs using a machine? I have been detailing by hand and the results have been great. I have used UC, #7 & #26 and the SUV looks great. Those products have given my Tahoe a very deep black color and minimal swirls are present. Also, I can vary the amount of pressure & speed I use depending on what I am trying to accomplish.
I have found that I apply the products a little lazy since I am working by hand and my arms tire out. But UC rarely needs to be used and #7 & #26 maybe 3 times a year so in that regard it is quite reasonable to 'go to town' when working by hand. And I don't have to tape anything up. But with the machine it provides a fast speed so is it the fast consistent speed the main factor of why using a d/a & rotary work well?
On a final note, I can't understand/appreciate something unless I have tried it out and so maybe working by machine is so much better; I don't know.
