I'd be interested to see how the yields would have changed had you simply topped and fimmed and scrogged and lst'd from the start, instead of chopping it down and having to give it a further 2 weeks to get back to a flower ready state.
I would not personally call this defoliation, more just extreme training prior to flowering. Your pictures show that upon flowering time, the plant was ANYTHING but defoliated. There may indeed be a specific definition of defoliation, but to me, unless it's being done in flower, then it is nothing mroe than a form of training, similar to what most of us do, be is lollipopping, topping, etc, but we wouldn't call it defoliating.
