Comment(by mhugent):

 Hm, the field calculator distance measurement sets oft always to off for
 the calculations. Therefore, it should always return 100.

 I tried it with your coordinates, and the field calculator always returned
 100 for me, no matter if oft-projection is on or off. So I think your
 preferred behaviour is already there.

 I agree that it would be good to have an option if otf and Ellipsoid
 should be considered or not.
