Following #4176, this is the last and fastest variant.
It is less precise but its speed is suitable for fast strategy:
it remains within noise level (<2%) even at negative compression levels (tested up to -7).

The compression ratio impact for negative compression levels is negligible, likely due to the disabling of the huffman literal compression stage, but nonetheless remains generally positive by a small margin.
