What you observe is completely normal. Set the point gap/dwell to spec and don't worry about it.
What CAN be an issue is cam lobe wear. If the point gap is correct by the dwell is not, then the cam lobe(s) have some wear on them. Worry more about the point gap spec, though, as that has to do with the ultimate durability/longevity of the point set.
IF you really want to get picky, use a dial indicator to check the point gap on EACH lobe. Which is where you'll see some differences between the various lobes, indicating wear, which will affect the dwell reading if the point gap is in spec. Which THEN makes the case for the more efficient and accurate electronic ignition system upgrade, FWIW. Be aware, too, that the particular breaker cam lobe you use to set the point gap might be different than the other lobes, which is what using the dial indicator really indicates significantly.
Be SURE to use the correct "point grease" to put on the rubbing block of the points!!! Many people in these modern times might not have any knowledge of such, especially since many brands deleted that little vial of grease from their point sets back in the 1980s. Mallory used to sell it in a larger tube, as did ACDelco. Specifically designed for point ignition point sets. Keeps the rubbing block from wearing down too soon and also keeps the breaker cam lobes from wearing too soon. Not greasing that rubbing block resulted from many electronic ignition kits getting sold in the 1980s, I suspect, as many related that the points in their older cars only lasted 8k miles, whereas we used to get 15k+ miles out of them in the 1970s and similar.
Just some thoughts,
