Looks like you anchored the base and tied down the top... looks good. the general concpet is about manipulating what's called: apical dominance... fancy word for which part of plant is dominating all the resources - i.e. most growth too. Among other factors, which branches is the tallest/highest will steal the most resources. Things that are roughly even, will grow more evenly. The bending of the plant tries to put multiple axillary buds or branches on the same playing field in this regard. even so, you may find some jumping ahead... simply bend it down or tie it down -- even if temporarily. use this method as a tool to impact growth of the plant to make the shape you want and a nice even canopy. i like to wat a bit longer -- Maybe, ~5 nodes above the bend at least. I try to make it fairly horizontal. Bend in more than one place to shape it well before tying down to avoid any potential snapping. even a 2nd tie-down in modle of horizontal trunk to help retain shape... again, try to bend and shape with hands first, then tie it down... at that point only needs to resist hydrostatic pressure in the plant, which doesn't take much at this point.
