Another observation re: data.

If you look at the first 17 bits of the inner track top color (l->r) against the first 17 bits of the outer track top color in same direction, they are identical.  I know you'd expect repeats even in random data but 17 bits in a row starting right on the boundary?  Odds are 1 in 131072 that'd happen?

inside colors
"000101010010110110", // outside track top, left to right

outside colors
"0001010100101101110010110000", // inside track top, left to right
