I figured that was the case; the black-and-white CFs just make easier
examples.  Back at the beginning of the thread, I recommend merging CFs that

had fixed-length rows and tended to both be read for some type of
operations, those would be a good candidate for merging.  Just take the
ideas from the black-and-white examples and apply them in a more nuanced
