As Valve stated, the win or the loss is the primary thing that alters your MMR (after the "smurf-detection" phase during the calibration matches where it includes other details with the hope that it will bring you to a proper MMR faster).
If they included extraneous details in how much your MMR went up or down, it would be abused by people prioritizing those details over the win or loss itself. For example, if KDR influenced it, you would find people not making the right play just to avoid dying. Although a bit barebone, the current strategy lets people die a bunch if they need to die, lets them sacrifice their GPM if they need to sacrifice it for the betterment of the chances of victory, and so on.

I always earn or loose 22-27 normally its 24/25 ( 80% of the time). Is this normal? I mean this doesn't reflect my performance in the games at all. It doesn't matter if you fail or not, the points are always the same. I thought there are other things that matter except win or lost, don't look like it.
