Other than the 1-26 class I not sure how the SSA RC has allowed anything other than Winscore in the past. *I see no problems using SeeYou Competition, like any scoring program you need experience with it. *There are a number of 'administrative' steps that become manual with SeeYou.

There is no rules-required official scoring program. Use a slide rule
if you want to. 1-26ers use their own program.
