Could somebody explain to me the significance of a game 1/2 - 0

Could somebody explain to me the significance of a game 1/2 + 0.
I don't see the rational

@Berettatiger Focus on blitz and rapid to improve. Have a good Christmas

It' was a draw and the player got zero rating points.

Edit: oops, seems like it "1/2 + 0" is a timecontrol, my bad

I thought it was a rarely seen draw/loss!

@Berettatiger Perhaps it is an intentional deviation from rationality... some people seem to find rationality to be oppressive. Actually, I think everyone pushes back on the rational side of their natures from time to time. Some more so then others. It's like the Prince song 'lets go crazy' or the Talking Heads 'stop making sense' and Radio Head has more than a few songs that elaborate on the theme of pushing back on rationality. ( Ironically, the 1/2-ultra player reading this post of mine would problably be repulsed by it: to much thinking involved.) Well anyways this was just my opinion or theory on the subject... food for thought I suppose. Just do your thing. Best of luck.
