Looking at it the wrong way.
It's not about how many mistakes, it's about how much room for improvement. Focus on that and it'll be more rewarding.
I already gave you a personal example of me getting good parses with lower scored teammates. Here's a random MNK I plucked as another example.

Yes it obviously has an impact, but it isn't as large as you imply. Good players will adjust and still put out great DPS regardless of their teammates.
Check the replay feature. It uses position data to recreate the fight in real time. You can see where the MT is (so which direction boss is facing) who is standing near who (so SCH was crowding you) and run it against timelines of abilities to see when telegraphs are out and where they'd be placed (based on people reacting and moving, or can be run against the incoming damage and see who got hit).Ok here I might actually not know something... I'm pretty sure though ACT and thus fflogs doesn't track position or movement and almost certainly cannot log where in an arena an aoe or telegraph is going to hit. nor can fflogs tell you I had to move because the sch was 1 step to my right or something like that ... if I am wrong and it can show this information then please do show me where...
I would take a 99th percentile i350 SAM ANYDAY over the garbage SAMs in PF.I think i'm quite clued with how logs works even if I don't use it regularly... so many things can affect your numbers that it creates an innacurate reading. I could for example play my samurai perfectially in the most optimal way and be the most skilled sam in the game (I'm not) but my sam being I350 instead of i370 for example might is gonna really impact my numbers. and no amount of player skill will ever compensate...
Further Example - my younger brother (a consistent top 5 world fury war in WoW), came back to the game briefly because he wanted to try out SAM. At ~i300 in Susano EX, he was putting out double the second highest DPS of people who were nearly 15 ilvl higher than him. It took average skilled nearly i330 SAMs to finally match his output that he did as a fresh 70.
I wish I could upvote this more. Great insight and good tips.
