Yes, you are right. Points are scored as follows, both in ERC and Junior ERC3:
Position 1 2 3 4 5 6 7 8 9 10
Points 25 18 15 12 10 8 6 4 2 1
In addition, bonus points are allocated to the top seven finishers at the end of each leg as follows: 7-6-5-4-3-2-1.
In Junior ERC3 only the best four rounds (from six) count.
The winner gets two rounds of the 2020 ERC in a ŠKODA Fabia R5.
