By conflict.
Gerhard Barkhorn who had 301 victories entered the war in 1940 and was not engaged in the Spanish civil war. Same thing with Erich Hartmann that scored 352 victories.
Thanks. Most of my historical interest in such lay in WWI. Richthofen (both of them), Voss, Fonck, Ball, Rickenbacker, etc. Amazing what they did in glorified kites.
