Similar for me, I draw an arrow <- or -> for my drive, UP arrow if in.Only F, L and R for Fairway hit, miss left or right, and M for missed short and # of putts.
I also mark GIR
Arrow for where I missed the green
# of Putts
I also mark on holes where I was in a bunker to track my sand stats. If I'm playing in a larger group I keep track of these on my own in my notebook, otherwise one scorecard works good for me by myself, it has enough lines!
