Here you print your max value, lets see where it comes from :

>'DEF:median='.${rrd}.':median:AVERAGE',

So you are getting the AVERAGE values from the RRD and printing the 
max of those. What you need to do is extract the MAX consolidation 
into a separate variable and print that, eg :

'DEF:maxvalue='.${rrd}.':median:MAXIMUM',
'GPRINT:maxvalue:MAX:Max Ping RTT (%.1lf %ss max)',
