While I do agree with you that Russian aircraft have definitely come out on the short end in most combat engagements (Gulf War, Vietnam, Israeli Wars etc.) , it is important to note that many of these aircraft were flown by pilots below the caliber of the average Soviet pilot.
Yes, I would agree that Russian pilots are generally undertrained and on average of lower quality than most NATO pilots, they do fly formidable fighters, and the Russians have a lot of them. Underestimating one's opponent can be a cardinal sin.
As for your point on Red Flag. DACT training isn't really an effective way of gauging how one fighter will fight against the other. EW, radar, and simulated weapons are nerfed significantly for security reasons. And even though the Indian Su-30s were Su-30s, they were flying with Indian tactics and Indian doctrine and thus they are not an exact analog to the GCI-focused Russian fighter doctrine.
Yes, the experience with the Su-30s at Red Flag does give the West a chance to experience how the Su-30 might fight, but the results need to be understood in context.

As you can see, the results of these exercises (especially those released to the public) are quite likely not accurate. And, for one side or the other to claim victory in one of these exercises is either dishonest or just plain ignorance. Normally, the results are released as a series of politically correct statements such as those we've seen by the authorities after Cope India. Both sides are happy, they learned a lot, and can't wait to do it again.
"I'm certainly not trying to stifle the spirited debate that goes on here. It's fun reading the arguments for and against various aircraft, however, be careful when you're quoting the results of some exercise when making your point!
I'm only saying that without details, all of this, "my airplane kicked your airplane's butt" is entertaining, but silly. One valuable part of the exercise is simply watching how the other side operates, what kind of tactics they use (they may have been "modified" along with the weapons), how they talk on the radio, etc. Obviously, the technology represented by the Su-30s is of great interest to the USAF also."
A USAF article on Cope India 04, not 100% relevant, but nonetheless a good article on Air-to-air exercises and understanding their outcomes.
