F-15 KD Ratio, is it 104 or 106?

Sam Eckholm's latest video on the F-15EX (that some of you may have watched) states that the F-15 has a KD ratio of 106 enemy aircraft downed to 0 losses from enemy aircraft. Ground fire and friendly fire are not counted. (Time stamp 6:05)

My question is, the previous 104-0 statistic was described with the criteria: "104 enemy aircraft shoot downs, 0 shot down by enemy aircraft, all kills made by Legacy F-15A/B/C/D Eagles." Essentially, only kills made by F-15A through F-15D counted towards the famous KD. (Or at least a few people told me it was this way)

So do the two Su-24s shot down by the F-15QAs count or not count? What are your thoughts?
