30 moves is like a million times easier than 20 moves. And 30 moves is not easy without backtracking and plenty of time.

What have you observed? Why does what you've observed suggest that there is a method that averages 20 moves or less?now your welcome to say this isn't possible, and im not sure it is, but based on what Ive observed, i believe it is.
If your willing to help, i can walk you through it and show you, if your just going to say "what you've found doesn't mean anything", I'm not going to waste my time.
I have come close to intuitively solving the cube within 30 moves just by observing how computers solve it.
Ok, what i have found is that, when a computer is solving the cube, it seems to orient certain pieces, then build a block of some sort, almost like ZZ, then, using the oriented pieces, it solves the rest of the cube in 7-10 moves.
A bit of a vague description. But it sounds somewhat like the two-phase algorithm: http://www.cs.brandeis.edu/~storer/JimPuzzles/RUBIK/Rubik3x3x3/READING/KociembaPage.pdf
1. Orient to <U,D,R2,L2,F2,B2>.
2. Solve.
For example:
D' R U F' D2 L F' D2 L U' F B2 U' R' F' B D' U2 R' F R2 D' F' can be solved:
U F2 D2 F U2 B' // orient edges, preserve some blocks (6)
D2 L' B2 D' L' F2 D' F2 D' F2 U2 L2 U B2 D2 R2 // finish (14)
My knowledge of how it works ends there, it's witchcraft to me.
Good observation!
I highly recommend that you read up on Thistlethwaite (and Human Thistlethwaite), Kociemba (also see my explanation), and Jaap's computer cubing page to see if you've thought of anything that isn't already well understood.
Chances are, there is no easy way for a human to find a short combination of orientation and permutation phases without spending a lot of time searching like a computer (or using a ton of lookup tables).
Was this sarcastic or real?
Ok, so I'm not completely crazy.
This is actually part of the method.
What's the Skype group?
has anyone tried looking at optimal solutions by computer programs and analyzing all the edge and corner cycles and looking if there are patterns of similar cycles/similar moves in the solution that repeat themselves?
i know i know, i'm just throwing some weird thought out of my twisted mind.
