I can't speak for Dave Woodward but I will. I spoke to him about this today. Dave has not seen the mag yet.
He tallied the results into a Excel file.
I think what happened is that when the file was printed out for the mag, Excel inserted a month in each of those cells. I believe what should be there is just the number.
Eliminate the month and just look at the number.
Dave, if I'm wrong please clarify. I've received a couple of phone calls about this and since it follows the Nats shoot report they thought I tallied the results.
