To stop causing confusion, we need to stop mentioning the term BOTS. It's been confirmed EA uses what is called ALGORITHMS to generate bogus matches.
The term BOTS would imply that a game/match was actually played out. As noticed many times, the plant load-outs seen are generating ludicrous, if not impossible scores that just can't happen in any legit game. This is because the plants are just displayed for aesthetics purposes (to fool you), and the scoring is algorithm based on your previous performance.
Thus, the harder you try to improve and score, the more you are penalized for it.
I've been thinking...If you know you are going to win a match in a legit game, you may want to stop trying to hit that 3 million score when the opponent is doing just 20K. Why blow him out of the water, and then have to deal with an inflated score to beat when the algorithm kicks in later? I believe it was stated on the OTHER forum that EA bases the algorithm significantly from your previous score(s). Then fudges numbers and tries to match it.
