What is capriole's bitcoin macro index?

Could you elaborate on the Capriole Bitcoin Macro Index? I'm curious to understand its purpose, methodology, and how it differs from other Bitcoin indices. Specifically, I'd like to know if it incorporates macroeconomic factors in its calculations, and if so, which ones. Additionally, I'm interested in its historical performance and how it has tracked the overall Bitcoin market. Is it widely used by investors and analysts as a benchmark for Bitcoin's performance? And finally, how frequently is the index updated to reflect the latest market conditions?
