With all due respect, I'm not sure what you wish for us to take from these videos.
One can find examples where many aircraft can beat another aircraft in training exercises, due to the skill of the pilots or the situation they were in. These examples and situations do not directly translate or have any meaningful relation to what happens in game. Both the Mirage 2000 S.5 and F-16A will have their flight models made as actuate as can be to real life performance data that we are able to obtain, with what information we can obtain.
All these videos show us is that in 4 separate individual situations, a Mirage 2000 pilot was able to best an F-16 in exercises. Im sure many pilots in game will be able to the same with the Mirage when the patch arrives. Equally, videos and / or pilots testimonies can be found that claim the English Electric Lightning was able to catch Concorde or "beast an F-15". We can do absolutely nothing with that information in game, as it provides no solid metrics on which to make any changes or base any flight model. They just happen to be individual occurrences and claims down to the pilots, the situation or the circumstances of the event.
If you believe something is specifically wrong with the performance of the F-16 or Mirage have have legally available declassified source material to use as your evidence, then please feel free to submit a report here and we can take a look
