OK, now step back from the computer and look at that critically.  It's
giving you a big clue on a silver platter.  Obviously you have a problem
putting the right value into the table.  Basically, you're skipping time
sometimes.  In that plot the main glitch lost about 1/4 cycle, which is
about 2ms if I understand the legend right.  Somewhere you've got a bug in
how the angle is being advanced, the timer behind it, or something.
