When is Set Over? Too Late to Correct Error?

[pavbref]

NFHS shore sheet has the score in two places: the running score and the server line. I scanned the server lines to ensure that each point was recorded. If the scorer is doing their job correctly, you can reconstruct the entire set. Also, if the R2 checks the score sheet at each time-out, the number of points that need to be scanned is reduced to the number scored since the last time-out.
