Top Metrics for Advocacy Dashboard and Benchmarking Advocate Accounts Against Industry Standards

Hiiii y'all! I'm working on building out the reports we want to use for our advocacy dashboard in Gainsight. I'd love to know what are your top 3-5 metrics to not forget, but in addition I'm thinking comparing our % of accounts with advocates to the industry standard would be super powerful and also help set expectations as we are responsible for growing the advocate base. I believe it's 5-10% of accounts are advocates, but I'm having trouble finding anything to back that up.
