In game quarters/halves

I was just curious if anyone else on here bets quarters/halves on the NBA. I just went back through my records and I've went 71-56(55.9%) since I started doing it, and if you take the past couple weeks, I went 40-67(59.7%). This is nothing great by any means, but it seems like the last few days that I was betting these before the all star break I was doing much better. And when I'm actually watching the game, I've done much better(I don't have the actual record, because I can't remember which games I did or didn't watch). Most of these bets came while I was glancing at ESPN mobile gamecast while I'm at work, and betting through sportsbooks mobile site.

Anyway, my main point of this post was to get the knowledge and feedback from other more experienced bettors/cappers out there so I can hopefully better myself, and maybe someone else can benefit too.

Thanks for any input you want to give!
