With that technique you essentially negate any size to your original plant. All you have is a developed root system. It now will either send new shoots from the root system or new growth will show in the "crotch" where a leaf branch\node meets the stem, i.e. suckers. Any advantage in time would be slight if at all in my opinion, either way you are having to wait for your cutting or sucker to recover and establish roots. That's the point I'm trying to make. Small suckers typically respond better to being cut and rooted as well in my opinion. I grow single and two stem plants and am constantly pruning suckers all year long. I've also seen it done where you put a tube or collar of sorts on a well developed sucker say over 12 inches, fasten to said sucker, fill with dirt, and let it root while still attached to the mother plant. You then cut branch and remove said collar and plant your newly established plant. I frequently get flower buds and have even had fruit set on plants that still reside in solo cups if my plant out is delayed. Same with nursery plants. Those have potential to be first fruits, the chopping technique I assume negates that. Just another reason I would plant as is and just wait for suckers. Jerryse obviously has success with his technique, and thats great. However I dont think thats a typical approach.
