As I pointed out on another thread, if you fly an approach one dot low you should actually touch down at the same point.
You will, however, have arrived having flown a shallower-angle approach. If you did this at the correct speed for your weight, you will have flown a higher-energy approach than the writer of the performance charts calculated. Your engine power will be higher (to maintain a shallower descent) and therefore will be slower to spool down when you chop the power. With a slower rate of descent you will spend longer in ground effect before touchdown, so you will be at a higher risk of tailstrike OR you will actually land longer or with a longer run-out.
All-in-all, not desirable. The physics of flying one-dot-low approaches do not help you. In fact, it makes your landing longer than it should be according to the book, all other factors being equal.
