So,
I was out today for a first try at shooting some footage/pictures. after all, these are flying cameras :-)

because I think the best way to learn is to do, measure, then do it again, I am really trying to get the hang of how to read flying data records, so I can try and correct my habits while flying.

Here's my latest flight today:

... and I more and more confused :-)

As you see, HD says my flight ends after ~5min, which is correct, while PH sees it as an interruption of signal lasting almost 27min!

Now, I definitevly know that it can't be possible: I powered off the drone, then the RC and then the Galaxy A3 I was using, in that order, and never powered them on again.
Where the heck those 27min came out I can't possibly know.

Also, can someone tell me what does the phrase "Downlink Restored (after 27m 15.3s); Forbin" mean? "For-what"?

It's just a spurious extra data point.  Ignore it.
It's uncommon but I have seen PhantomHelp do that on one other occasion.
