Yes, but it's not my context.

Context of the reply thread…

... which was itself in the context of a device for civilians. To avoid litigating the primacy of nested contexts in a casual conversation, maybe let's agree to not be so picky about which caveats are on topic?

Not really. Most serious lap swimmers can do a kilometer every 20 minutes sustainably, akin to a marathon runner's pace (Sprint pace would be 100m/minute, with 50m/minute being what you would see in the fast lane of most recreational pools). So 3.6 kph isn't all that different, maybe a little faster than average but I assume they were also using a better-than-average bicycle person when doing the test. There real adv…

A mid tier marathon runner can do a mile every 20 mins, not a kilometer. It’s a significant difference.

This is besides the point but a 20 minute mile is a typical walking pace, not anywhere near a mid tier marathon pace (regardless of the definition of mid tier). That would be an 8:40 marathon.

A reply is always in the context of the thing that is being replied on. It’s how replies work…

If there is an article about berries and you say you love blueberries and I reply saying “I hate them”, it in the context of blueberries. It doesn’t mean I hate all berries. And I shouldn’t have to clarify that, since I’m replying to a comment about blueberries.

How else could this work?

And everything is always in exactly one easily defined context, right? So for a comment reply we already know the full context just by looking at its immediate parent. That's how nested replies work, right?

Really? Go into the next HN thread and see how many deeply nested comments you can make sense of by looking only at their parent.

That's a really odd mistranslation, given the Italian words for lightweight and light source are as different as in french (leggero/a vs luce). Looks like it was translated directly from the English content.

From the looks of the scuba diving video, it looks worse. There's way more leg movement and it looks less controlled (and more likely to damage corals/kick up sand from the bottom) than slow finning.

Given the number of times I've been kicked in the face by another person's fins while scuba diving, I wouldn't want to be anywhere near someone using one of these.

Looks fun until both your regs are wrapped around the prop six times.
