The root-opt phase is insignificant in time as a fraction of poly search time at this size, so I choose something big; I don't think there's any / much difference between 35 and 50, but I pick 40. ...

Agreed, I'll start poly select Monday afternoon after this last run of curves completes.

Max's 'spin' can yield a 5-8% improvement for one poly vs another, so I would say posting anything within 10% of the expected best is worthwhile. For this job, we should get to 2.5x, so I'd say...
