Notes:

• Written on request for a fellow OARC member. It can be adapted for other countries, programs and years by tweaking the values at the top
• Includes a 1-second delay after every API call to avoid hammering the API. This means that as of March 2025 it takes ~2 hours to run.
• Includes SES and club calls as well as personal calls
• Does not do any special handling suffixes such as /P
• Won't count anyone from the UK who activated only overseas parks, or anyone from abroad that activated UK parks
• Will double count folks who have changed licence level during the year and activated using both calls
