So, this is like the 3x3 example solve thread but only for the Mehta method.
If you don't know, the Mehta method is an algorithm-reliant method that solves the cube in the following order:
First block on the D layer.
3 edges of the E layer or 3QB for short.
Orient edges (Algorithmically) while solving the last edge or EOLE for short.
Orient last 6 corners (using 1 alg) or 6CO for short .
Permute last 6 corners (using 1 alg) or 6CP for short.
Algorithmic L5EP

(or there is a beginner variant which does the last 4 steps in 2 looks each and a ZB variant that algorithmically solves the DR block after EOLE thus, giving you a ZBLL finish)
There are 3 more variants with which you can do option select.

That's it for the introduction let's move on to the solves:

Scramble: U2 F2 R' U2 L2 F U' D2 R U2 L2 D' R2 L2 U' L2 U2 L2 F2

Solution:

U2 L E2 L' E' z //FB
R E R2 u' R U R' u' R U R' E R U R' F R' F' R //Long belt

U R2 D' R U2 R' D R U2 R //6CO-2
U' R2 U R2 //D layer corners+lucky DR block
U' x R2 D2 R U R' D2 R U' R x' // PLL Ab Perm

Beginners version(kinda) but got lucky.

This thread might be of interest to @Jam88 , @BenChristman1 @Devagio and @CuberStache and a few more people but please do try it.
 
So, this is like the 3x3 example solve thread but only for the Mehta method.
This is a great idea! This way the example solves page will not overflow with Mehta examples and we could digress into discussing particular solutions freely.

Interesting observation: There is not a single anticlockwise quarter turn in this scramble. In a 20 move random-move scramble, the probability of this happening is 0.03%, roughly the same as a ZBLL skip.

Beginners but with a 3 move 6CO1 and a 4 move APDR lol

Also, switched back to ACN from cubeDB for recons

There's no next scramble, so I'll use Cubing Forever's again.

But it's not a random move scramble but instead a random state scramble.
