I bought Dorico 5 upgrade this week. In the program there's Learning videos, and I watched this one first, since I've used Dorico 3.5 doing scoring. It's really informative with Hit Points and adding meter to make the Hit Points work a lot better ( than digging into the time code fix).
If you're starting to write with these elements, there's 2-3 videos before.
Hope it helps your scoring ( no matter what Notation pgm. you use).
