I've upset a fair few people by not sharing but when I used to, people would come back and think they had a right to tell me how what I'm saying was nonsense or how it is a placebo so I said bugger it, let them worry about it (online multiplayer) whilst I enjoy it.
What I've learned within the last 3 months would make explaining what I'm doing with the R1 and every COD and BF game a task, maybe 2-3 pages worth and I have no drive for that and those who were almost practically begging for it were very rude when I'd share some of it anyway, I just gave up.
Jitter is most important, the lower the jitter the less it matters if your round trip latency is a little higher than normal. Almost half of my fix was physical, on the line, sadly my ISP wasn't any willing to help, thankfully I was patient and learned how to fix it myself (HFC cable broadband).
I used to share my settings but I no longer do that. My games are consistent 90+% of the time in BO3. Hit detection is a constant now, sometimes I just get it wrong with the way I play, making noob mistakes like not looking at the map enough.
