Switched to specifying bit length as a quotient for the purposes of a PCMSegment and verified that I had the logic for picking a Commodore time zone backwards: bigger numbers are faster, not slower.
Started sketching out a DiskDrive class.

Switched to a full-on linear regression. Which causes the current tests to pass.

Made a quick-hack attempt at PLL synchronisation. Which doesn't work.

Started sketching out the basic form here, albeit that it doesn't yet do _the only thing it advertises itself as useful for_.

Sketched out an interface for a digial PLL. Not persuaded yet. Baby steps.

Factored out the PCM track since it's going to be a useful construct for almost every file format. Documented it a little better.

Actually, I think this is the correct conversion from received speed to clock rate. It'll become obvious if it's not when I get back to working on the 1541 itself.

Put sufficiently much of PCMTrack into place to get to a stored list of segments, having determined a common clock rate between them and therefore a complete track length.
