"Race an activity" is a mutant? Partly also a navigation, partly not? And why fixed extra data screens with redundant datafield?

Today was the first day that I tested how Race an activity function. worked I am quite pro in course nav and in Pace Pro, I used the dfifferent combo of navigation settings etc.

So today I was surprised. In many ways.

1)

First because two extra data screens appeared and they seemed to be fix. Moreover while it is logical that a Virtual Partner datascreen appeared with two data (Time Ahead/behind and Estimated Finish Time), it seemed to be quite illogical to get a 2nd screen with three data from which the middle one was Estimated Finish Time.

Wow! I could not disable them, I could not modify them, they did not pop up in the Navigation settings. as options. See also below

2)

By the way Navigation settings. I played with all the options and some of them had effect, on shown data and some of them had not. Eg. enabling Elevation profile did nothing, that data screen was not added. On the other hand if I enable the extra datafield on map, it was added as was the normal datascreens numbered from 1, 2 etc..

Up Ahead was not added if I enabled it. And not the Heaing bug, nor the Guide screen.

3)

Finally I realized that Race an activity does not really trigger navigation, because my extra data field on map is next turn, which showed nothing during the activity. I even left the path of the earlier activity I raced as a test and I got no Off course warning at all.

So apart from showing or hiding Map either with or w/o the extra data field, and showing or hiding the normal data screens actually Navigation settings had zero link with Race an activity as a pure training option. .

I see it just the opposite way? Why are these screens shown if actually we do not run any navigation? They are part of Navigation settings and navigation screens should be shown when navigating, should not it?

EDIT: and "certainly"  the manuals of F7 and E2 does not mention the 2nd extra data screen, just the VP datascreen.

EDIT 2: If one digs he finds a supprt article implying this 2nd one, but with different data.

I still believe that the three data I saw could not have been disabled
