The person who made the chart simply went off of values found currently in the files. He did not claim R-77-1 would be better than AIM-120C-5. The only person who made ridiculous claims so far is you.
Lets rehash the false claims here so far:
R-77-1 has only a 10% range increase over R-77 (you)
according to you they only moved it down because US players are so bad while it actually overperforms so you should agree with me (it was also never moved down, just not put up)
In 2015, the US entered service with AIM-120D while Russia received R-77-1 the same year. AIM-120C entered service much earlier. Europe simultaneously entered service with Meteor as well.
I really don’t get your point. The R-77-1 is a work in progress at the moment, exactly like the Aim120C5 is. The values tested as of July have zero indication on their future performances ingame.
Especially as Gaijin consistently murdered everything flying in the soviet tree for the past year.
If anything, that is something you should ask AusChalk since he wanted to go by what was seen in the files. I simply corrected him as to what was available in the current files, nothing more nothing less. R-77-1 can drastically change in the future, but as it stands right now in the files it dominates everything else, so statements such as “it has less drag than R-77 in the files” or it has “10% more range than R-77” is incorrect.
