Mr. Google knows both American and York rounds… Both shot on standard 122 FITA (World Archery) Target and Imperial scoring: Yellow 9, Red 7, Blue 5, Black 3 and White 1.
American shot from 60, 50 & 40 yards in that order. 30 arrows from each in sets of 6. Historically you should shoot each 6 set by shooting first 3 arrows, step away from the line for a short break and then shoot another 3 arrows but most skip this today.
York Round is real manhood test: 12 x 6 arrows from 100 yards, 8 x 6 from 80 yards and 6 x 6 from 60 yards.
I don’t go through those indoor games now because it’s summer time and outdoor season coming.
