add a time period designation for all metrics, eg per day, per week, per month, etc

[gruns]

afaict the explorer's compiled stats are per week. but this isn't mentioned so the reader isn't sure if they're daily, weekly, monthly, or otherwise

without a time period, all the metrics -- like 1B requests, 700TB bandwidth, etc -- lose meaning. is that 1B requests per day? per week? per month? etc

explicitly state a time period for all the metrics 🙂
