we should finally document them in the man page. Do this here.

+CSV FORMAT
+----------
+
+With -x, perf stat is able to output a not-quite-CSV format output
+(commas in the output are not put into "")
+
+The fields are in this order:
+
+ - optional usec time stamp in fractions of second (with -I xxx)
+ - unit of the counter value or empty
+ - event name
+ - counter value
+ - run time of counter
+ - percentage of measurement time the counter was running
+ - optional metric value
+ - optional unit of metric
+
+Additional metrics may be printed with all earlier fields being empty.
