Funny thread. Whoever said deluded was right. 8 is a barrier for most. 6 another barrier. I'd say 2 and below another massive leap... You're a good 11 shots shy of it.
Its not just the 11 shots though is it. Its the number of rounds needed to get down that far, for which you can also interspace the bad rounds that give 0.1 back.
I'm yet to see anyone comedown linearly. Most come down in steps(plateau's) with the odd step up amongst them all.
