The "Top Performance Medal" requires you to finish in the 'Top 3' fifteen times, and shows a counter underneath of how many times you've done it.
As for strategy: Yeah, yeah, yeah you can just camp in an easy position but I hate campers and refuse to use any kind of tactic revolving around sitting in the same spot for ten minutes.
So I just used my rush-tactic like in every shooter I play :D
The important part is, that it doesn't matter how often you die. My Kill/Death ratio is terrible but I still get around 400-500 points per game which is enough in most cases to be in the top three.
The most important thing you want to use is the defensive support. The hardest part is getting to 50 points. I can assure that you don't need to camp and just can run around. After you played the maps a few times you will know where most people hide and will also earn badges.
After you hit the 50 points, don't use it. You get 25 points for using it, so you need at least another 25 points to get to the next tier. If you die, you will still have the support available. So now you only have to get 25 points, which is one normal and one melee/headshot/revenge/savier kill. Then use the defensive support to get to 50, which earns you another support.
With this tactic I had no problem finishing in the top 3. Don't be encouraged if you fail. You will evantually get it. Just wanted to post a solution that doesn't involve a cheap tactic ;P
You must be in the top 3 of the scoreboard a total of 10 times. The best way to do this is to earn streaks, and capture/destroy objectives. If you are not good at FPS games, then I would recommend playing an objective game and go for the objectives. If you are good at FPS games, I would still recommend going for the objectives, unless it is too risky and you might die, resulting in losing your streak. When you get a Killstreak Reward, your safest option to get the most points you can get in a game is to choose the Defensive Support Streak by pressing . If there are many enemies beside each other and you know how to use the Offensive Support Streaks properly, then use that instead by pressing . Earning and using Killstreak Rewards is the best way to get in the top 3 of the scoreboard. Good luck!
May take some time, especially now since the online community is much smaller and limited game modes. However that said it's also easier in a way since if you end up in a game of 6 you only have to beat 3 other players in score.
Easier in a mode with objectives to get score and also use defensive streaks over offensive for guaranteeing yourself more points as fast as possible. That said good luck
*MUST BE TOP 3 OVERALL NOT JUST YOUR TEAM FOR TROPHY TO COUNT*
UNOBTAINABLE DUE TO SERVER CLOSURE
You need to be the Overall Top 3 in a match 10 times to obtain this trophy. Multiplayer experiences vary from individual to individual, but in my experience any objective based match like Sector Control, Combat Mission and Objective Raid is easier to do this because you get points for completing objectives and it doesn't turn into a mindless kill-fest or K/D ratio centered game like Team Deathmatch. You can track your progress in your Stats screen under the Awards tab. On the lower right there is a medal that is awarded for achieving Overall Top 3 fifteen times, and a counter on the screen below showing your progress towards it so far.
