As far as we understood (just finished one of the german qualification tournaments on Sunday), a tile with a scoring element is just a tile which has inclination, so if the tiles go like this:
then one would have tiles with scoring elements on position 1,2,4 and 6, could place checkpoint markers on 3 and 5 (and of course on tiles 0 and 7 if they are tiles without scoring elements) and would earn a total of 15 points when passing this section, because 1 and 2 would count as one long ramp¹ giving 5 points in total and 4 and 6 would gain 5 points each.
Maybe one of the TC members wants to confirm my example
Regards from Germany,
¹ However when counting the tiles for gaining points after 3.5.3, the tiles 1) and 2) count as two tiles.
