I do believe if you aren't given a p that you're supposed to use .5. I'm not sure that I'm applying this rule on the correct subject, but does that sound familiar to you?

I just realized you don't have an N either. I don't suppose they mean errors in a foot? i.e. out of 200? (That's a little weird but it's all I can think of.)
