Hi Michael,
referring to B.Safonov, I can add that Yuriy Rybin appear to be a very serious and scrupulous researcher. Apart from various articles, in 2018 he published a biographical book titled "Boris Safonov" (unfortunately only in Swedish!) where there is detailed list of Safonov's victory claims (see attached). The individual claims are 20 (14 obtained with I-16) but only one shared (1/2). Maybe the other shared victories are not quoted due to the high number of pilots involved and the consequent low effectiveness of Safonov himself obtaining them. The only difference with M. Bykov list is victory nr.4: 17/07/41 (23:00-23:45) according to Rybin, 18/07/41 according to Bykov.
