Whether Beags can come up with the statistics or not it is quite irrelevant - when the NPPL was introduced it was obvious that those most likely to be first in the queue would be those who had been excluded from the PPL for medical reasons as they would, in a large number of cases, have already held PPLs at some point or would have been keen to do so were it not for the medical considerations.
Far more interesting would be -
What proportion of PPLs do anything with their licence that they couldn't do with an NPPL?
Why are they committed to spending more money than they need to?
What proportion of PPLs never even make it to the first renewal?
