My dear Green, in my company we have some of your Lufthansa Flight Training stars and they are not the best...moreover, one of the worst FOs as a person in my company has just been DLR positive after failing 2 PCs in a row...but he is German, blonde and tall.
If the DLR is only for Germans...that's OK...but if I pass or not the DLR it is not because I am or not within limits after having almost 8,000 hrs / 5 different authorities ATPLs / three type ratings / not accident or incident records.
Besides...German pilots also crash aircraft like any other...
