The classic example was their nuclear research project. There was
a period in late 44 when both Heisenberg and Diebner were
running parallel programs and both required heavy water.
There was only enough for one or the other but the German
reaction was to give each a portion

Diebner did not require any heavy water in late 44,that the reason why he
succeded and why British troops seized more than 10t heavy water in a warehouse
in Hamburg.
You also forgat to mention Houtermans and von Ardenne.
