It sounds like you are saying the points would always be open. They won't...they'll be off the same 5ish degrees the cam is off, but they will still open and close normally. There is so much adjustment range available in the points that you could still set them to break when the "S" mark is in the sight hole.

So if you were off in this senario, it would be hard to see slack in the follower/ points, so maybe you could be off in one direction, but I would think you could detect the slack between the follower and points if you were to look closely (may have to use a magnifying glass).

There cannot be 'slack' between the points, rod, and cam under any circumstances. The spring in the points keeps the pushrod in contact with the points and cam. If it was floating, you wouldn't be able to run the engine, let alone time it.
Heck, take the crank out, and the cam, pushrod, and points will still operate the same way...
