Thank you.

Twice as fast as what? Have you tried it against 'lzip -0'?

What is the difference with the matchfinders that have been tried and 
discarded in lzip 1.11?

have been tested and found no better than the current BT4.

Waiting for the comparison with 'lzip -0', my first impression is that it is 
not worth the trouble of breaking lzip's reproducibility.

Best regards,
