+# rate vs irate
+
+    irate(v range-vector) calculates the per-second instant rate of increase of the time series in the range vector. This is based on the last two data points. 
+
+    irate should only be used when graphing volatile, fast-moving counters. Use rate for alerts and slow-moving counters, as brief changes in the rate can reset the FOR clause and graphs consisting entirely of rare spikes are hard to read.
