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`.
104`, the best dual stepper result is `SET ticks 269`, and the best
three stepper result is `SET ticks 472`.
