For example, is the following transformation correct?

gdaltransform -s_srs epsg:31466 -t_srs epsg:4326
2534000 5490000
6.46925611791806 49.5458035746045 5.23711311891839
2534000 5580000
6.4771846139954 50.3549233866055 3.37402869747075
 2644000 5490000
7.9886508632139 49.5296632215733 4.35285628430074
2644000 5580000
8.02222474710927 50.3383168074372 2.4900523843271

That is latitude ranging from 49.5458035746045 to 50.3549233866055

Then I should use option 6 (?)

It just that I am not sure about the exact transformation parameters.
