I haven't seen the lower number and have used 80 on all the T and A mains. While I do use the 80, if the slot is really not lined up, I grind a little off the back of the nut and try again or swap the nuts around. There is a reason that wrenches are made in different lengths, they are designed so that a wrench of X length can only be pulled so far in normal use. I have done a little checking, giving a good steady pull on the main nut wench till it stops moving yields about 80 foot pounds when checked wit a torque wrench.
