I never noticed it on my regular singer machine. I have a Babylock Esante ese2 - and when I didn't put the tension back to "automatic" it balled up in a huge knot - did it twice....put the tension on "automatic" and I got a perfect bobbin.
You may be right - it may only be on some machines...maybe those with electronic/computerized adjustments???
