Which would have done nothing - the low penetration on a bolt that they used and Greek armour and formation would have meant that they were just wasting fire.
No. Again, the bows shown in the video are not for combat use. Would you compare an air rifle to a combat rifle?
I thought you didn't have time for this
I don't. It's bad for me

Before we go down this same dark road again, how about we lay down a few tenets; agree on some, and agree to disagree on others, pending proof.
1. That video represents pretty much the way a mass produced cho-ko-nu is depicted in wiki. It's really a hand crossbow with repeating fire. This is what the peasant levies would have.
I don't think peasant levies were really what you're looking at, though. Sure they would have a significant presence, but psiloi are also peasants. You might ask what Greek peasants would be doing in China, but the Macedonian taxeis was recruited largely by region and this was done to reduce the numbers of people in restive areas for political purposes. Naturally, plenty of peasants are going to be part of it.

2. Han dynasty (as you mentioned) armies had more powerful composite cho ko nus, so it is reasonable that the Qin armies have some of these in their regular units, but they are not as light and fast firing, and it is still a relatively small crossbow in power despite its bulk. I don't know what the effective armor penetration range would be, maybe 50 yards ? - but not shield and armour.
Maybe not 50 yards, and the phalanx front was very resistant to arrows. However, numbers, as I said before, are what needs to be accounted for here. Unlike in Europa Barbarorum, phalanxes are not nearly invincible from the front. Projectiles would get in here and there, and with enough numbers the shields would be encumbered. Bad shields are bad for the phalanx. Certainly, the crossbows and especially Zhu Ge Nus would devastate the psiloi. Not sure what Alexander would have made of that, or whether he could expect it. The lighter crossbows would be sufficient for this purpose, leaving the heavier ones for use prior the actual engagement.
One thing to note, if crossbows can work against armoured elephants, they can certainly work against heavy infantry.

3. Regardless, I don't see anybody sustaining 10 rounds every 15 seconds indefinitely without the thing jamming or eventually breaking. It's a weapon of numbers - it isn't made that rugged or precise - and I don't see every peasant soldier arming these barbs with fast acting poison either. As Flying Pig said, some of these darts would land on unprotected horses or exposed flesh.
I don't really like talking much about the Zhu Ge Nu, since I don't think it will be present in significant enough numbers. The poison thing seems also kind of marginal. I don't know. There are accounts of poison arrows being used in the Romance of the Three Kingdoms, but the practicality of it on a large scale is questionable to me.

4. The cho ko nu is not an arbalest, in fact that term itself refers to late medieval crossbows that in essence may have appeared earlier in China. They could have as much draw weight as a longbow, but only fired twice a minute, and required a well trained corps. You are right the quarrel was intended more for a flat trajectory, hence reduced range.
Keep in mind that the range of bows at that time probably did not match medieval English longbows, so the crossbows would have had significant range. About the well-trained thing, a crossbow required less training than normal bows. The training in question would probably be more about discipline and normal infantry drills. Also remember that the crossbowmen are also pretty much the Chinese version of heavy infantry.

5. About longbows: They required more skill to master than the crossbow, but had about 4 times the rate of fire. In fact archers such as this had bone and muscle deformities from their continued use. The killing range of the longbow in the Hundred Years War has been described variously but around 250 yards, and that was against armoured men. (There is a concurrent article on Roman vs. Medieval armies with some good info) Maybe your friend from Warwick castle was measuring the effect against the impractically heavy armour that came about as a response to this. But I'm sure you can find some exotic crossbows that exceeded this; neither they nor the English longbow are relevant to this though. The maximum range of big composite bows from the Assyrian Iron Age is given as 650 yards.
250 yards of armor piercing is unbelievable. That would be more powerful than gunpowder weapons. Yes, the 50 yards thing is probably for plate armour (and he wasn't my friend, he was just a demonstrator

), though I'm not sure as some plate would be resistant to almost any arrow. But in your example armour may mean studded leather or something, which is still a far cry from mail or scale that existed since ancient times. And heavy armour was very practical, otherwise the cuirass wouldn't still be in use in the 18th to 19th century.
Anyway, you're talking about a relatively advanced bow. You can scale it down in this scenario, so I wouldn't be positive about armour piercing at much greater range than that. 650 yards of maximum range is probably not very effective for much. Most archers would wait till enemies get a lot closer. I think, all considered, I'm pretty sure the crossbow would have a range comparable to most bows of the time and pack more punch in general.

6. Philip and Alexander's light troops (Thracian Peltasts, Phrygian skirmishers, Cretan Archers, and slingers) were highly specialized experts, who were more suited to wearing down melee infantry formations, but they could be adapted to this role. The famed Agrianians and other javelin troops needed to close to about 30m but were singularly effective against all but heavily armoured men. I base this on books on ancient warfare and it seems to be the same on wiki.
Yes, there are peltasts besides psiloi. The hypaspistai might even be used in a similar role. But they wouldn't represent such a large force and they would still have to beware of the light crossbows, though, as their role required light armour.
Slingers are something to be considered, but they don't form a significant part of any ancient army I know. Probably has something to do with the fact that they need to be trained or experienced and are thus quite rare and valuable.
