I know seems pointless when FMQ but this is how I learned the right speed becaue I know for myself I tend to go faster around curves and loops. try not making any "sudden" moves either it can pull the bobbin!
above all practice, change the tension just a little at a time and sew some, see if it gets better. if not change it again!
Good luck! and Welcome!
