This means nothing. I intentionally typed in the title of several novels that I happen to know are bestsellers. Two of those, The Bridges of Madison County and The Miracle Life of Edgar Mint, came up with only a 10.2% chance of being bestsellers. Which goes to show, this little test has no actual merit when it comes to predicting what will actually sell. It's merely based on analytic probability-evidently, for example, titles containing the preposition "of" seem to have an automatic mark against them. But as reality has proven, those kinds of statistics have little value when it actually comes to what people will or will not read. It's a fun game, but take it for what it's worth. Don't go into a panic thinking you must suddenly change your title.
