[One Winged Angel]

I have no intentions of changing the way difficulties are determined, but if SDGs are producing skill rating scores that most players don't deem to be entirely accurate, I'm assuming the formula can easily be tweaked to reflect this.

There's no way to say with absolute certainty that 7g on a 60 is worth specifically the equivalent of a 50.XXX whatever AAA, they're just approximations (someone like prawn or trumpet could elaborate more on how these numbers were achieved). Just know that in terms of official tourney placements and what not, players will still be placed on a case by case basis with individual combing through levelranks. I wouldn't worry a great deal about being misplaced because of one or two outlier scores that are outside of your general skill range.
