Assume you have unlimited scion wood and rootstock. All scion wood and rooststock are pencil-sized. You are a beginner grafter (so no 5-second whip-and-tongue) and you can use any tool or supply you want. What grafting technique and supplies would you use if time was your main restriction, and you want to maximize total successful grafts, not % success. So, if you can do 30 grafts in an hour, of which 15 are a success, that would be preferred over doing 10 grafts an hour, with 9 being a success.
I would think one would not do the W&T with a sharp knife, with buddy tape, Temflex, sealing the whole scion with Dr Farwell grafting seal, but perhaps a faster method of using a U-Cut grafting tool, with a quick electrical tape wrap to seal/support and a quick drop of wood glue on top of the scion to close the biggest source of evaporation?
You want a technique that maximizes success.
Every failed graft is time wasted. Precision = speed = efficiency
You definitely want to avoid electrical tape, temflex etc. because that requires you to go back and remove the wrap or it’s a choked out graft. More time wasted with after care. Learn to tie a half hitch with a rubber band.
Bud grafts are very time efficient. Buddy tape is ideal as it will stretch without breaking like parafilm. More time wasted with parafilm.
W/T are also very time efficient. The tongue holds the graft in place when you wrap. Whip grafts waste time. Take time to learn the skill of one single cut instead of whittling.
I would buy the 4T Grafting tool and use a lot of the english double v cuts. I am using a Chinese grafting tool with the Omega cut. But! If you do not do periodically sharpen the blade you can get messy cuts.
So far keeping the back up blade sharpened with a fine round rat file, followed by the diamond round rat keeps them very sharp.
Probably 65% of my grafting is done that way. The rest by knife.
I have had few issues with inexpensive green self adhesive grafting tape backed by electrical tape.
