I don't expect this to generate much activity, but if we want to consider the stainless-skulls-helmet thoroughly spaded, it needs a lot more testing recorded. The Techniques Testing page is awkward to use, so I made a spreadsheet anyone can edit:

It's probably a thankless job – there may well be no new results – but there it is.
Perhaps more useful, if anyone wants to create a similar document, you can get an auto-updating list of all page names tagged with "technique" at techniques-alphabetically.
