You didn't say what you play. Is it ca, ffa, tdm, etc. Do you know what your skill rating is? T4 is 75 and over. 100 and over will get you the gold bar. To check your skill rating, go into an EMPTY server of whatever game mode you play, and type /serverinfo in the console, then scroll up and see what the server skill rating is (sv_skillrating). If there is more than you in the server, then the skill rating will be an average of all the players present. And remember that t4 has no upward limit of skill. You can have a 100sr with the gold bar and play someone in the 900's and they will make you feel like a complete noob.
edit...as an example, my ffa sr is 953 and yet I have plenty of matches where I'm lucky to get 30 frags. Check my match log for last night playing a guy called fgt. You'll see what I mean.
