Hello Nick Beale thanks for the interesting piece of info on I./JG 2.
On the JG 2 generally (and MTO)
IMHO Mark R. / Mark J. Reardon’s message #4 on 7th April 2011 14:32 for the actual research on the USAAF reported P-38 losses and the LW P-38 claims during the Tunisia Campaign and Rob Romero’s #25 on 20th April 2011, 20:24 for the stats calculated from it give a good indication of the variation of claim accuracy of different units.
see:

Rob’s main result were
JG 51 19/25: 76.0%
JG 27 -2/-3: 66.7%
JG 53 19/29: 65.5%
JG 77 -7/11: 63.6%
JG 2 -5/22: 22.7%
the sample of JG 27 is very small but IMHO generally LW claims were at that time and area very accurate, those of JG 51 almost exceptionally accurate but again JG 2 was an exception, overclaiming badly.
