What are the units on the vertical axes for figures 1 and 2? I might have guessed seconds per TiB but the braiding line doesn't seem to match what's in figure 3.

I forget, these were the outputs of my test scripts and I wasn't exactly fastidious here, at least the axes all start from zero :)
IIRC they're off by maybe a factor of 10 or 100, the test scripts just generate a bunch of (seeded) random data and then execute the CRC of X bits Y times and that's where the number comes from, it's consistent across the different tests even if the units are wrong
