Nonrandom time series floats are often significantly helped by delta-compression before applying the actual block compression algorithm. I used to do this quite successfully in late 90s when sending FOREX quotes to clients over analog modem connections.

You'll have better compression with lossy compression and better precision with user controlled and bounded relative error. see for ex. this benchmark for scientific data: https://github.com/powturbo/TurboTranspose https://github.com/powturbo/TurboTranspose
