At least according to this guy, and considering he's the only one who has bothered to learn any of it I'd say he's probably right
I've seen this guy before. It's cool what he can do. I put this multiple arrow hold in my story including having the character learn the technique from reading about it. Not the polished version but this is it. And the skill comes back in once near the end of the story. Mark climbed up on the large boulder that sat on the edge of the clearing. It provided him a perch a meter off the ground. He pulled three arrows at once from his quill and in one swift movement put them between different fingers. It looked awkward, a splay of arrows like a fan, but the arrows held. Continuing in one fluid movement, he jumped off the rock taking aim at the target by feel, not sight, the bow never reaching his eye level. The arrows loosed one at a time, thut thut thut, almost too fast to see. When his feet hit the ground, all three arrows hung firmly clustered in the bullseye.
Really? It is just me that finds a grown man jumping around like a maniac with a bow and arrow incredibly funny? Looks like it must be.
For some reason I have images of French knights at Agincourt riding back to their own archers and telling them. "I got some more arrows for you, just pull them out of my chest when you need them."
Oh no, not just you! I can easily picture a warrior from 'back in the day' finding it incredibly funny, too—for about 0.2 seconds (0.4 seconds if his two buddies bite the dirt first). The most amazing part of this is that there were people far more skilled than Lars in that time. I can't even imagine what that was like.
I don't think it's any funnier than grown men playing football or basketball. Andersen looks like someone incredibly skilled to me. You want funny? How about fastest gamer thumbs in the West?
I had heard a report somewhere, and damn me if I can find it, by a European who had seen gurkturks on horseback drilling and said they could fire off 20 arrows in 20 seconds. I assumed either that his numbers were inflated (as historical accounts universally are) or that the turks had some kind of secret method. Seeing this guy work I totally believe it. Of course the turks were on galloping horses on which they had ridden since they were toddlers. So I guess we have to wait while Lars astral projects back to his childhood, and learns to ride before he can walk, in order to see something like that.
Slower, about a bolt every 1.5 seconds. Lars has been clocked at an arrow every .6 seconds. Edited to add: And aim wasn't a priority in working a repeating crossbow as it had to be shot stationary and from the hip.
Wow! I wonder how many hours his clocked in to become that good. I mean, it can look easy to us, but anyone who's really, really good at something knows you have to put a lot of effort into becoming that good. Well, usually anyway. I remember once seeing a documentary of some guy who could mimic pros just by looking at them do their thing.
What strikes me is that he makes drawing the bow seem effortless, so either he's got great strength or it's a very light draw weight.
I've seen this guy's video and he's definitely using a very low-poundage bow. You need only look at how little penetration his arrows get (at very sort distances) I'd like to see him try to catch something coming at him at 210 fps (from a recurve bow) or 300fps+ from a compound. I've heard somewhere that he's been debunked, though I haven't bothered to look it up. Also, you might want to use the term "quiver" for a container of arrows. You might want to rework your first sentence to "Mark climbed onto the large boulder at the edge of the clearing." or similar, for a start. Nowadays, we refer to the act of "shooting" arrows, not "loosing."
I have to agree that this is quite amusing despite being really cool. As for the actual technical aspects of archery demonstrated in this video, it really doesn't surprise me. Just like jesters and circus actors or even modern day performers, people excel at their trait, so to think that an archer who has been training for most part of his life would stand still in a battle lining up a shot is actually quite absurd. There was probably people back in the medieval days that would put this guy to shame in terms of technique and skill. In fact, Japanese archers were very similar to this, especially from ninja clans.
