Trying to figure out Fenix 6 “Race Activity” fields

I went out for a paddle today, and had both my Forerunner 920XT and my Fenix 6X on my foot strap, and both set up to “Race an Activity” with the same 10km activity selected. The course I was racing had 57:08.3 as the base time. I had my GoPro so I could grab some shots of both screens. I am doing this because I can’t for the life of me figure out what some of the fields are on the Fenix. I know what fields I need on the 920XT, but the equivalent fields on the Fenix are either in different places, or they show utterly insane values.

First set of pictures

This picture is quite early on in the paddle. The 920XT is showing a Estimated Finish Time of 55:21, and Time Ahead of 0:11. So it thinks I’m going 11 seconds faster than the activity I’m racing. Since the difference between the target time of 57:08.3 and the estimated finish time of 55:31 is more than 11 seconds, I assume it means I’m 11 seconds ahead right now, but if I keep it up I’ll finish in 55:21. On the Fenix side, the Estimated Finish Time is 1:01:23. I have no idea why it thinks I’m 6 minutes slower than the 920XT. But here’s the insane part: The Time Behind is showing 42:07:48. WHERE THE FUCK IS THAT 42 HOURS COMING FROM!!! Even if the 42 represents something other than hours, if the time behind is 7:42, I’m trying to figure out what that mathematically relates to, because the estimated finish time is only 4:14 behind the goal time, not 7:42.

First Set.

Another screen shot around the same time. The top one is labelled “ETE”, I think that’s time remaining. The middle one is distance remaining (9.49 km, so about 500 meters into the “race”). I’m not sure, but I think the bottom one is actually an estimate of the clock time when I’m expected to finish.

Second Set.

This is further along. I assume the prominent number in the middle is the estimated total time? The top one is distance remaining (5.47 km). That syncs up nicely with the 920XT saying I’ve completed 4.53 km.

Second Set.

This is seconds after the previous one. The Fenix is showing an utterly useless map. If there’s a way to zoom this in so it would be more useful, I haven’t discovered it.

Second Set.

And a few seconds later. The Fenix is showing the same distance remaining, although this time in the prominent middle position. The top field is, as I mentioned in the second screen shot, apparently the estimated time to completion. The bottom one is the estimated clock time at completion. No idea why I’d want to know that.

Second Set.

Here’s that baffling “Time Behind” again, still with the strange “42”. The estimated finish time at the bottom of 59:20 lines up OK with the 58:12 earlier in this second set of pictures because I had to stop paddling to take these so I’m getting slower with each shot. But again, even ignoring the “42” in the top field doesn’t make sense, because again, 59:20 is 2:11 slower than the goal time, not 6:39.

I wish there was some documentation on what these fields were, and I wish there was a way to customize them.
