I guess I'm not an LST follower. I used to tie down branches and leave it, but I don't anymore for a handful of reasons. I approach training like most things. In moderation. Sometimes I super crop, or top. Sometimes I roll the stems in my fingers with some pressure until they soften. It bruises and damages the stem and has to be repaired. The repairs strengthen it. The branch has to pick itself back up. Bonus: this makes my fingers smell great. Sometimes I pony tail and leaf tuck for hours or a whole day by accident. Sometimes in veg I'll wrap my fist lightly around the bottom of a branch and move upward while bending gently outward. It's like petting a cats tail. The idea here is to train the branches out from the base of the plant while reinforcing them with scar tissue which will help support future weight. That's the theory. In conclusion, I combine LST and HST in an effort to make my plants do exactly what I want instead of following any singular philosophy or technique. I call it MST for moderate stress training.
There are lots of techniques that are recommended for photos that aren't recommended for autos. That's not to say they don't work for you, they're just not what most auto growers suggest, particularly for first or second-timers.
Supercropping is not something I see many growers of autoflowers do, as injuring the plant slows down the growth during the recovery period. Autos don't give you recovery time, particularly not at the age that one would supercrop. LST is the safest for autos and can increase yield greatly. My untrained outdoor blueberry auto gave me 49 grams. My LST version of the same plant gave me over 150 grams. When topping autos, it's done very early and usually not on your first grow of a given strain, as some can take getting topped and some just stall after the injury.
Whatever works for you is the best technique, but low stress is almost always recommended for autos over the HST techniques, and even by the the growweedeasy.com site that many 420 growers refer to for techniques:
