+The test was last run on commit `01d2183f` with gcc version `avr-gcc
+(GCC) 5.4.0`. Both the 16Mhz and 20Mhz tests were run using simulavr
 configured for an atmega644p (previous tests have confirmed simulavr
 results match tests on both a 16Mhz at90usb and a 16Mhz atmega2560).
 On both 16Mhz and 20Mhz the best single stepper result is `SET ticks
-106`, the best dual stepper result is `SET ticks 276`, and the best
-three stepper result is `SET ticks 481`.
