I am testing it right now and it seems to be as good as the smart algorithm though the guide star gets drawn inside the square better. Still, I get an overall RMS of 0.6" which is great! And coming back to your comment indilib.org/forum/general/3251-guding-go....html?start=12#25437
in the Guiding Gone Wild topic, I am doing this on the RPi3 running Ubuntu Mate and the latest KStars stable build directly via pulse guiding on the EQMod cable so no ST4 guiding. Great!
