I didn't realize you were talking about the other file "stretch". I had figured that was just some sort of interim file used for creation of hist.csv, since I couldn't make sense of it (only two columns in v1).
So I haven't even inspected any stretch.csv data at all. But I can now.
And the downloads thus worked as expected. I used separately named folders, so I have both v1 and also v2 which makes the 5-column stretch.csv.
