Here's a hint : Your friend knows he was parsing so he used optimum timer on ability/engaging mobs, etc.. while the other didnt know so they were just doing like usual merit pt when you see someone idling for 30s before coming quick to the mob and start hitting.
Just that can have a big impact on your parser result.
Also if the parse was on colibri, the 5 acc can actually do a difference depends on what equip he's using with and what equip have the Black Belt monk.
