If you plot the correlation of consecutive pairs of bytes, it looks like this. The bright dot is 102, which repeats itself a fair bit at the start. The horizontal and vertical lines are 63,64,191,192 as every 8th number is one of those four values. Most of the space is 0. when a pattern appears once, it usually appears more than once. 2,4,6,8,10,12 all appear frequently.
