2011.10.30 - Counting to 30 8 times

This recording is of me counting to 30 8 times. I was wondering what it would sound like if I recorded myself counting to 30 but without a clock to keep me in time and how accurate I could be. I was surprisingly close except twice. You can hear that I do start to get faster or slower after the 15 seconds mark. This was recorded using a Zoom H-1 digital recorder.
