I'm wavering between the vivoactive 3 and the 645 and have some questions regarding number of fields on data pages for activities. On the vivoactive, I know that the number of data fields has some limitations compared to the 645. You can select 1,2,3 or 4 fields per data screen, but all the data screens need to have the same number of fields. So if you want 4 fields on the 1st screen, the 2nd and 3rd pages all have to have 4 fields. My question is, does this limitation go across activities. For example, if I have 4 fields on running, does biking also have to have 4 fields.
Also, if the number of fields can be different between activities, can I set up a second running activity and give it only 3 fields per page.
This really becomes an issue if you want to use any of the IQ data pages for running that require a single field. Then all your pages would require 1 data fields which is very limiting.
