In 45k miles the nylon just isn't as long as it used to be and the dwell is different and therefore your timing has moved. Unless of course you have done maintenance. Yes I know what you're probably thinking, the car ran fine, lol.

I put a dwell meter on it once a year, never had to touch the adjustment for many years.
Usually what I find (have 4 cars with points) is that an initial new set of points requires a few periodic checks, and usually a quick adjustment, but after a few thousand miles they tend to settle in and I simply don't have to adjust anything. I still make it a routine to check it once a year but I never find they need anything despite the internet rumors.
Here's the car with a 20 year old set of points in it. As I usually do once a year, or when planning a track outing, I toss on the dwell meter and check it. It's always a rock solid 30 degrees. Simply didn't have to touch it. Like I said, later on that same year, last year, I was talked into replacing the points. The plastic rubbing block was virtually identical to the new set going in. It showed no excessive wear anyplace. These things, if installed properly, using a "good" set of points, oiled correctly, and in a good points distributor that isn't worn or wobbling, are dead nuts reliable and require very little maintenance.
