For piecing, my stitch is a little bit smaller than 2.0 on my Bernina. This may be because I prefer to press my seams open.
More likely, though, it's because my very first sewing teacher complimented me on how much thread I had committed to my project. That terrycloth bathrobe still serves me, >35 years later. Of course, had she not insisted that I add lots of "ease" to the pattern, it wouldn't fit me at all these days. What a wise woman!
