Having data does not imply usefully analyzing it, and "experience" is nothing more than a plurality of anecdote. Without actually seeing the data, I think your best guess here should be 50/50, rather than the very biased-toward-the-high-end "more likely (of course not 100%)" that you have. Appeal to authority is especially dangerous when you are making decisions that affect your company's bottom line based on peoples' ability to format text.
