I factored:
69^99 C145
88^94 C143
I had some other ~C140s from other sources (like my own 13^n aliquot work) that I've also been cracking.
I've removed these two from post #684.
I'll do 88^92...

I factored:

It's nice to work on just a single params file, trying lots of different settings. Sadly, I have not yet found the magic key to the 10-15% more...

--server-threads controls the maximum number of threads CADO uses for any phase of the factorization.

CADO is very fast for GNFS on smallish inputs- on a Ryzen 5950 I have factored a C127 in 59 minutes, C119 in 25 minutes, C111 in 8.5 minutes, RSA100 in 2 min 51 sec.

The last step CADO takes in a factorization job with workdir in /tmp is to delete the work folder. If CADO does not finish for any reason, the folder isn't deleted.
