Regarding the Outerverse and Regeneration discussion I will get to that ones I have made my new account. It is just easier to have a conversation with the rest of the staff that way. I will also get a new router soon (it should have been today, but got delayed apparently) and I will do the account creation afterwards. This also means I might not respond the next few days, should things get troublesome.

In regards to the lightning articles: Many of those state the low end of our article (100000 m/s = 220000 miles per hour) as speed, while not specifing wether it's an average, a low or a high end. I actually know some of these, but always assumed they take the low endgiven that nothing suggests otherwise.

The second one just states 100000 m/s or higher actually.

The last two links are those that are interesting.

From those the second one doesn't cite sources and is not a study from what I see, meaning that I don't know where they got their values from.

What one sees from those two already, though, is that such studies due to building averages over  different lightning samples get different results. The last one say 1 to 2, the one before that 2.5 to 3.0.

I think it is more likely that the change in values is because of the samples taken than because of changing to more modern measuring equipement.

I think writing that different samples resulted in lower averages, with a reference to this study is a good idea. It should be noted that this studys mean values at the top are the geometric mean, which is ≤ the usual arithmetic mean. The arithemtic mean value is 330 000 m/s, as mentioned further down.

I wouldn't recommend the change to 220 000 m/s, as suggested by the poster, as I think he misread the 220 000 miles per hour in any of the articles for that value, given that 220 000 m/s is actually not mentioned.

All in all I don't think the evidence here is pressing.

For convenience sake I would suggest leaving it at the value we have, with the mentioned nod to other results.

If the other staff members think a more modern article is necessary I would suggest the 330 000 m/s mean value of the article linked above, as it is the highest quality one source wise and, aside from the last article he linked, the only one that mentions wether the value is average, low or high end.
