.000 - Holey Moley - or, porous forus.
.005 - Skeet - which in Lower Slobovian means "missed again".
.010 - Improved Syllable, that syllable being obscene.
.015 - Lightly Mortified, as the bird sails off.
.020 - Mortified, or just enough choke to cause a near miss.
.025 - Improved Mortified, same as above but a far miss.
.030 - Way too Much - perfect for when the bird is twice as far as it was.
.040 - Extra Too Much - or, sky busters delight.
