What is the polling rate for the tag history binding in perspective?

For historical ranges, there’s no polling - the query is run for whatever time slice is given. If you change the end date binding to a binding that poll (eg, `now(5000)` then it’ll update to the current time every five seconds, and that becomes the de facto poll rate for your binding.
