Do the Archery rules cover this?

Have a look at G.T. Dennis' translation of the Strategikon attributed to Emperor Maurice, anything by David Niccole, or the book Arab Archery and A 14th-Century Archery Treatise in Mamluk-Kipchak: Kitab fi ‘Ilm an-Nushshab.

Because it is just a video meant to attract attention, I am not treating it as harshly as I would someone who made claims in writing and insisted that they were scientific or historical fact. I am actually impressed that you can do this in GURPS!

I think that our source for rapid shooting is a test for Mamelukes which required them to shoot three arrows at 70 m range so that the third was in the air before the first hit the target. Given range and velocity one can estimate time. But I doubt that they let Mamelukes cheat with light bows and very short draws.
