I have dabbled in contests mainly to collect states and entities, and have occasionally sent in check logs. I just worked the CQ WPX RTTY contest, and would like to submit my logs for credit but the primitive logging system I used doesn't calculate the score. To compute a "claimed score" requires me to determine the number of unique prefixes.
Frankly, I'd rather not compute a score at all and just let the contest organizers do it (since they will anyhow). I wonder what the "claimed score" is used for - perhaps in cases where there is a large discrepancy between the claimed score and their computed score they take a look at the log?
I'll add that for the 2023 CQ WW DX SSB where I submitted check logs, they sent me information that showed how my logs were scored including QSOs that were disallowed - it was very interesting and useful.
What should I fill in for the CLAIMED-SCORE field?
