bzip's window is 900k, yet it compresses 100MB to 29% but 1GB to 25%. Increasing the memory on 7zip's PPM makes a larger difference on 1GB than 100MB, so maybe it's the window that's relevant there, but it doesn't seem very plausible to me. (18.5% -> 17.8% vs 21.3% -> 21.1%)

Sporting lists might compress badly, especially if they contain times, but this one seems to compress well.

That's very odd. If you ever find out what is going on here, I'd appreciate knowing.
