What is it's rating in your estimation? This would probably be good to play against for practice.

Against an human I think it could be around 1700/1800. Against other softwares, it is rated below ELO 1600 (you can see rating for Satana, that was its previous name).

I don't like to play against softwares but this one is fun to ply against, from an human point of view.

Live testing of Sabrina 3.1.24 here:

It seems that I've gained a lot of ELO, with re-deepening: from 1480 to about 1610 (G6 ELO).

I was wrong: it hasn't been re-deepening the reason of the ELO gain. Still I don't know what happened, because the RD was not called at all (do to a mistake in implementation) but still the program were stronger than in the previous test.

This is a big mistery!
