The sim gives you canned data and all at once. This is something you want to look at on a real device, as there new history is added only every minute or two at most.
Measuring the pressure vs saving it to history are two different things Measuring I believe is every second - that's what you see in the screen shot next to Baro:
Last I checked, history was saved something like every couple minutes on a real device, but It's been awhile since I checked that. You can look at the difference between "when" in two samples on a real device.
