That info is available multiple places for many common rear derailleurs (including your site as I recall), but I've literally never seen it published for ANY front derailleur. (My apologies if that level of detail about rear derailleurs is on your site and I missed it somehow.)

That type of detailed info would be incredibly nice to have. It could be useful for predicting what FD/family of FDs might work cross-brand with another manufacturer's indexed front shifter(s). However, the proof is always a functional test.

I guess I'll either have to keep looking, or start measuring. Don't really have access to enough hardware for the latter, so it will almost certainly be "keep looking".
