Power zones are imported well from TP, presumably because most people use 6 or 7 power zones as standard. TPV assumes the same for HR, but a 5-zone system is more common. Every time I open TPV, my Zone 1/2 boundary and Zone 2/3 boundary are the same, presumably because I have only 5 HR zones defined in TP. Each subsequent zone boundary is off by one zone compared to my TP zones. If the number of zones cannot be imported from TP, then I request that the imported zones are justified to Zone 1/2, rather than Zone 6/7.
