Nice job, Stig. Is that like doing 1000 squats?
If you do it right, yes.
If you don't squat, you have to bend your back, and no-one has a back that'll hold up to that.
So teaching the new kids how, is mainly getting the method right, then the numbers will follow.
But good apprentices will want to show that they can keep up, so they wear them selves completely out at first.
This kid is still in the try-out phase, that is why I added the insult of putting 1000 in the ground in 6 hours. In bad soil, with clay just 5" under the topsoil.
Not many can do that, good planters do 1000 in a day.
I was lucky enough to have a mentor, whose special skill was slim lining work procedures. ( The guy who died last sunday)
I have benefitted from that my whole career.
Never a wasted move, whatever I do.
I teach my apprentices the same way.
If you fall a tree that your bar can reach through, you should be able to do it in 3 cuts, without shifting your feet.
