I’m not a speed sewer at all, not even close! Longarm is faster than when I’m piecing, but not super fast either. Like all things, different speeds for different folks. When I took a longarm class I needed a couple of practice tops since I had no tops ready, I purchased 2 practice tops on Etsy, and was appalled at the seams. I spent several hours ripping and re-sewing them. Some seams were totally missed altogether, some were less than an 1/8 of a inch, etc. . I reached out to the seller and expressed my concerns and she stated that she was a “speed sewer” and it never occurred to her to check her work when she was done. 😳
