My guess would be better approximation as you avoid a “fluke”, as 8 second is a very short time where nothing could easily happen even with crickets being present

Oh yeah, the US and the one country next to them, whom they exported all their norms and culture to should definitely be a standard for the entire world, aye?

Actually, literally the entire world excepted the US does call them “United States of America”, if not only “United States”, with traductions of those. The French use “États-Unis”, often not specifying America, as do the Spanish speaking world with “Estados unidos”. And, yeah, we often just say “Germany”, 'cause Germany doesn’t try to appropriately the name for the entirety of the continent they sit on, like that one weirdo country does.

My two cents are the following : avoid irritation as much as you can. This means doing as few passes as you can, if possible shaving somewhat less often, and/or shave less close to the skin, for exemple using an electric trimmer. You should wash beforehand using hot water, and afterwards using cold water, and then dry before moisturising. I personally use and beeswax and olive oil based cream but a lot of products will do the trick. Remember that every skin is different, and sometimes, you can do everything right and still have symptoms, so you should adjust your shaving habits to accommodate those
