NOAA graphs at https://gml.noaa.gov/ccgg/trends/weekly.html

As examples

February 2024 MLO level is 423.50 or lower then claim resolves at 0%

February 2024 MLO level is 423.74 then claim resolves at 24%

February 2024 MLO level is 424.50 or higher then claim resolves at 100%

Resolution will be soon after data made available likely ~5-8 March 2024. Close date may be pushed back until after the data is available.
