What node to top for outdoor grow?

I've read 6 others say double that.
Looking for the most bud.
Size of plant doesnt matter for stealth. Looking for whatever method will yield the most

Also, what node to top side branches, I've read 3 or 4. Does that sound right and is that for all branches top to bottom?

6 is when I top and always turn out good

There is no concrete rule about this. Some plants grow better and produce bigger buds without any topping at all.
If you want more yield, veg longer and plant in a bigger pot/hole.
