It is big news, authors have been reluctant to release any shred of evidence except to say Kurt T outran P-51's in his Ta variant. but there was not proof that JG 301 serving on the Ost front ever encountered P-51's at altitude, only mid alt. Soviet a/c types. So then again it was not an expectation at all ....... you may feel it is no big deal but it is an enlightening one compared to what has been in text and ridiculous web-sites in supposed authority without further research
