IM FL 2008: Timing Weirdness

So my finish time was 11:36. I looked at my watch and noticed that my stopwatch read 11:32. Where did 4 minutes go? I’m pretty sure I would have remembered starting it again if I had noticed it stopped. All my splits were pretty consistent, with the exception of T1 where I forgot to hit the split button. Weird. Was I running so fast that I entered a time warp and lost 4 minutes somewhere in local Dshen time?
