My core argument is that you are choosing to interpret a Phantasmal Beasts turning slower than Servants, as meaning that this Phantasmal beast could not be fast enough to turn to evade a projectile in this circumstance, which does not have to be the case.  

As an aside, one of the archers that was covering me was player by you? Was their a specific reason why the Matou Archer did not fire? 

Anyway, you have outlined the arguments as you see them, so, will you give me an answer to my request?
