Don't take reference desk statistics too seriously. It's not like anyone ever looks at those tally sheets anyway.
Recording tick marks and classifying them as "Reference Transactions," "Directional Questions," or "Phone Calls" is a pitiful way to justify our self-worth as professionals. Sure, an administrator may occasionally make a staffing decision using this data, but when was the last time an administrator came to you and said, "You know... I was just looking at the reference desk statistics, and I think we should add another reference librarian to help you out during your busy Thursday evening shift"?
Ticked off with tick marks? Librarians should take a principled stand and ignore the useless act all together.
