i see in the map command, you're using earliest=-6m@m but in the timechart you're using span=60m. I'm curious if that is a typo on one or the other, because you wouldn't need to span 60 minutes in a timechart if you're only looking 6 minutes back. also, at the end of your map command, you don't really need the table command, because those fields are all the fields in your stats command and will automatically generate in a table. Also, do you really need 100000000000000000000000000000 searches?
You could also flip your where and sort statements so that you aren't sorting on so many lines.
Last, but not least, | count does not do anything, you need | stats count in front of it to work if you're trying to count how many rows where greater than 95, in which case you really didn't need the sort at all.
