I didn't read and watch those links, I already know a bit about bows. Basically plate armor was extremely effective against arrows and I think that shows in game pretty much unless an archer with high powerdraw + one of the top tier bows hits you. This mod isn't entirely realistic but most don't want it that way either. Also arrow velocities while important are not the only factor in penetration. The weight of the arrow is another huge factor. A heavy arrow has all that mass 'piling' up on itself when it hits. If we want to talk more realism crossbows would be near useless at range ( they would however be very scary up close). But this is a game and the consensus is fun over realism for most.
