The easiest way to increase the number of
good shots per round... is to decrease the number of bad shots per round.
At some point in the set (it happens to
everyone) you lose the ability to hit
good shots. Wherever that is in your set (the #3, #4, #5 or #6 iron) remove
the offending clubs. You will hit fewer bad shots - and more good shots -
every round. Better yet...
