No. If you punched all the holes out of the card (a so-called 'lace card'), 
it wouldn't go thru the reader. It was 7 or 8 bits per column. Even binary 
punched on the card was spread out so it wouldn't make too many holes.

Some of them were very fast. Most were closer to 5 or 10, unless you had a 
really high-end giant machine.
