ROC Curve = Too Complex!!

I recently submitted to a nice little manuscript that several colleagues and i put together that looked at the diagnostic validity of oral reading fluency in predicting reading comprehension. I thought that a Receiver Operating Characteristic Curve analysis would be appropriate, but little did i know that a little convex curve would nearly cost publication...

"ROC is not commonly used in education and although the procedure used for generating the ROC information appears to be correct, it is too complex an analysis and is better suited and understood by the medical world"

I guess if I had inserted some unicorns, it would have distracted the evil curve :)
