    Are you sure about the first question? I know the data is TRANSMITTED every 2.5 minutes. But that’s not really the UPDATE rate. Reading Scott Dennstaedt report, which seems to be your reference, he’s still saying 4-9 minutes.

      As you noted (and as mentioned in Scott’s report), there are latencies that mean that the data will be more than 2 minutes old by the time you receive and view it – that’s true.

      But the question was how often it is updated, which is every 2 minutes.
