I see lots of dark round circles amidst the grey rubble that I would assume to be holes. Additionally the grey rubble area measures roughly 200mx100m on Google Earth, or about 4 football pitches in area.
Only hangars/bunkers were targets, not the entire field.
With all my optimistic view, I can only count 7 hits…which is not that bad for such relatively small area (7 X 1000 lbs).
And for fun, a representation of 76 cruise missiles on Barzeh :
