Considering how much screen space each activity takes in the feed, which is almost entire screen, it is strange there is enough space for only 2 or 3 activity metrics. Often it is just distance and elevation gain, and even duration isn't shown, like in the screenshot below. Imagine someone doing a monster effort and spending 30+ hours doing an ultrarun, and then the time ends up not being shown so others cannot fully appreciate the effort. Arguably, spending that much time on feet is an achievement by itself.
Furthermore, in the example below, why there are only two fields shown? There is enough space for the 3rd field. But it seems the horizontal space is taken by the "Achievements" word which I think is completely redundant.
And furthermore, I think the feed would likely be much improved by taking two rows to display activity fields.
