Because of the different tooth count on each gear, it will take many many revolutions before that bright link comes back to the very top. As long as the crank and cam marks are coming back to the top every couple of rotations (and nothing is binding up like valves and pistons) then it sounds like you got it right.


Yes, you would probably need to figure out the least common multiple of the sprocket tooth count and the number of links o chain to figure out how many rotations it'll take to repeat the shiny link position.
