Not really, you would have to dump what you have and feed it in to a 
new database. But apart from re-consolidating the data (which will 
obviously have an effect on the accuracy), there is no way you can 
ever get a meaningful MAX value from an average. Consider this 
sequence :
0 0 0 0 0 0 0 0 0 100

Average is 10, max is 100 !
