This is silly, but I think my FR255 gives an audible beep and vibration for some auto lap alerts and only a vibration on others. Today it occurred to me that I heard it for the even numbers, e.g. lap/mile 2 and 4 but not for lap/mile 1 and 3. I felt the vibration for mile 3 but heard nothing, and I somehow completely missed the first lap notification.
Has anybody else noticed anything like that?
