How do I see what a reading is actually based on?

On Now, one line says how many sources, runs and nights of sleep Trailwise is using. The full list, What Trailwise is counting, is on Seven signals. It says how many sources are connected, how many runs are recorded and how many nights of sleep sit behind what you are reading, and how much more it needs before the charts settle. Where a figure is thin it is labelled an early estimate rather than dressed up as a final number. For today's call, Show what this used beside Trailwise's reason lists what was read and what was held back.
