There's all sorts of philosophies on when to shift. Don't worry too much about what others are doing. If you can shift at lower RPMs without lugging, and want to do so, go for it. My 2013 MT Passat LOVED cruising at 1600 RPM, with no shudder at all. Honestly it could go down to 1400 RPM if there was very little load (gentle downhill slope, for example). Some wouldn't go that low because there's little power for rapid acceleration, but there's always room for personal preference in these discussions. Like some of the gurus on here say, "Drive more. Worry less."Why do all the folks with manual newer TDIs on here say you should be shifting no lower than 2500rpm cold and around 3000-3500rpm warm if the DSGs shift SO MUCH EARLIER?! And I also regularly read that anything below 1800rpm is lugging the engine - what gives, are you concerned?!
