Pretty similar method here
I go one per pot, top once then knock tips of at least twice to get more branching for more fruit sites. also pick off any early flowers and keep doing that until happy with the size of the bush. Adds a bit of time to the grow but I've given away lots of scorpion plants to people and I tend to out yield them 3 to 1 growing like this. Not saying its the best way but I reckon its a lot more effective than letting them do their thing.
I basically apply lots of weed techniques and it seems to work well
