Man you crotchety old guys are _hard_core_. And nitpickery.<br>
<br>
I manage to wrangle my mean clock error down to about 0.09ms per 50ms loop<br>
(measured over 1000 iterations, even under system load), so less than a<br>
tenth of a millisecond error on a 50ms loop is just not good enough?!<br>
<br>
Woof. Woof woof and more woof.<br>
<br>
But *clearly* Ima gonna havata do bettera, or its le scarpe di cemento.<br>
Maybe down to una microsecondo prima del molo dei pescatori è il mio destino.<br>

I've updated the code so it's now a proper class with YAML configuration,<br>
etc. and updated the github repo at:<br>

[For those of us building robots on platforms that don't have access to<br>
fancy hardware clocks, we have to make do somehow. Ima tryin.]<br>
