My first deg 5 effort with CADO to admax = 2e5, the result being a very high skew (and apparently incapable of improvement or scoring by cownoise) poly:

It is as VBCurtis and Gimarel predicted - searching on low values of a5 produces untenable polynomials. I’m bailing on my reserved range of admax = 3e6. Instead reserving admin = 1e9 for a range of 1e6. Will start searching with a smaller chunk of 100,000 just to see if CADO produces useful quintics.

And I will try bumping nq to 15625.
