Hmm.....no offence but i seriously doubt that source of yours. TaiwanAirPower.com? come on.....
A good site that I use for database info on A2A victories is
Although the site may lack accuracy and a bibliography, it sure is convenient.
In numbers of A2A kills, as in aircraft vs aircraft, excluding ground based sams and recon drones, the Rocaf holdes a clear lead over the Plaaf. However, it should be remeber that during the 1959's, sidewinder equipt f-86's inclicted heavy loses on the Plaaf mig-17s. This was quite a predictable result, seeing as how the Pla pilots had absolutely no strategical or psychological preperation for such a weapon. By the time that China had gotten the Attols, the series of air engagements was over.
In light of current aircraft inventories and experience, I would say that both sides are about equal, seeing as how its f-16s, which has a remarkable record for shooting down mig-21s and 29s, to su-27s, which also has a remarkable reputation for shooting down mig 21s and mig 29s. The booast that Rocaf get up to 300 hours of flight time per year on f-16s is also bs, due both to engine run time/resupplies, and that fact that not even the USNAF, the most overly funded airforce in the world, get that much.
Here is a link to the Su-27s 0:7 kill ratio agunist mig29s
Has quite a big a catching up to do with its counterpart the f-15 don't you think.......
