You're not so much averaging as seeing what you hit the most, ie what you're most consistent at. From the looks of it, 13/12 takes the cake for seconds. Reason it's two and not one number is most likely because you're not totally consistent with mashing "a" to get to past the continue screen.
What you do next is dependent on whether or not you're using emloop or pikatimer. If pikatimer, you're fine since you'll be going for higher delays and possibly higher seconds anyways. With emloop, you really need to narrow your second values down to 1 number.
