> Duration 4 years (02017-02020) ... a single event within a six month period starting no later than Dec 31 02020 Am I the only one who finds the terms above terribly ill-defined? Let's suppose an event happens on Dec 31 2020, and a million casualties accumulate over the first few months of 2021. Does that count? It counts because it's within a six month period starting Dec 31 2020. It doesn't count because the duration of the bet was 2017 to 2020, and therefore wouldn't include 2021. Wouldn't have been less confusing to state the terms as "within a six month period ending no later than Dec 31 02020" (if that's what was intended)? What if the event happened on Jan 15 2021 followed by a million casualties. Does that count? Jan 15 2021 is within "a six month period starting no later than Dec 31 02020". If that's the case, the duration of the bet is 2017 to Jun 30 2021.
