Liveview AF not accurate?

I was playing around with my 7D and my new 100L macro tonight, and noticed that the AF in liveview is not as accurate as normal 'quick mode' AF (where the mirror flips up) (It was only marginally out but still noticable)

I was always let to believe that contrast detect AF was much slower, but always accurate. Any ideas what might be going on? My 24-70 was bang on with the LV AF.

Im not overly concerned - actually I was chuffed at how accurate normal AF is with this combo, but its got me scratching my head. Could there be some sort of incompatibility with them?
