^^According to scorehero you need 404,670 for 4-stars.
I stopped playing regularly a while back and just recently started playing frequently again maybe 2 weeks ago in anticipation of GH:A. I feel like I'm actually as good or better than I was and I've been pushing my career score ever higher. The thing is that the beginning of TTFAF still kills me every time.
Part of my problem is that I literally don't have full use of my left hand due to a shattered elbow from when I was in Jr High (damaged nerves, they heal very slowly). My pinky doesn't cooperate like it needs to (ie does its own thing typically) and while I can get along without it by going for raw speed in a lot of other songs this intro just doesn't allow for it, you pretty much need your pinky (or do the two handed thing but I suck awful at that).
On the flip side when it comes to songs with extensive solos like The Devil Went Down to Georgia I do very well. I can beat the devil probably 2 out 3 times now with the 1 time I don't usually being due to a lefty flip during a solo (still can't get used to that one). I've had a chance to play the 360 version a while back with the DLC Boss Pack and I remember I 4-starred it, I remember it primarily because I was in a public place so I had a lot of people staring at me like I was (to borrow a line from Yahtzee) "A freak with a trained pet spider working the buttons".
I'm still working on TTFAF but its frustrating knowing that if my GD pinky would do what its told I'm beyond confident I could smash the solos. But unfortunately its part of the song and the more I work at it the more I actually help rehabilitate my hand...just in the past 6 months or so its gotten significantly better. So eventually I should regain full use (or so they tell me) and finally beat this damn song.
I'm breaking 300k now in practice mode at least....
