With entirely too much time on my hands, I've been working on a "Universal" W&B Excel Spreadsheet to include all the DA40 variants. The net effect is the main page has the various loading envelopes overlaid. There are three data points in this example which represent the loading of the NG that stalled in the UK, for which we have the accident report (see "Hangar Talk"). The points show T/O, zero fuel and empty weights/CGs for this plane/incident.
The lower weight bounds of the envelopes are largely meaningless, but the lower bound for the NG does represent the minimum weight specified as a limitation. There is no such limit specified for the other versions.
I find the empty weight/cg numbers for the accident airplane interesting. I was under the impression the empty CG for these tended to be more like the older DA40's like mine. To wit, around 95.5 in. This plane is depicted at 97.4. This makes the rear CG limit a bit more challenging than with an extra 2-ish inches to play with.
