Real-time accuracy is greatly improved. Pace, distance, etc. We did a 2 mile test. My suunto 5 logged 2.01 miles exactly. The suunto 3 logged 2.04 miles. Before the variance was .1 to.2 miles.
I will try to gather more details, but I don’t think the wife will ever want to run without using the GPS Connected app locking the GPS.
Thanks,
