So true Prism99. No silly questions here. 52 and 53 are the serpentine stitches. Janome, Brother, BabyLock are all made by the same company. I could be wrong but I don't see how or why the serpentine stitches would vary between these machines. I consider serpentine stitch a decorative stitch for sure. It's great for quilting and the different looks available by lengthening or shortening the length and width are amazing. Happy Snaking you all.
