Unfortunately, your 7x7 solves don’t have the capacity of having consciousness, nor are they a physical object or being, so I am unable to complete that task.

hey I'm not a beginner i average around 20 secs on 3x3 and just got a 7x7 does anyone know how many parity's there are on a 7x7? And if so what are there algorithims.

There are still only 2 parities that can happen on 7x7, although they can happen multiple times each. The algorithms are the same as on 5x5, which are the same for 4x4, just adapted slightly to account for the center slice.

Treat L2C like F2L (or F2B, since you're a Rouxer): look at the algs to make sure you know what the efficient solutions are, but learn them by looking at how the pieces split apart and join together.

Priority for L2E algs should be (from highest to lowest):
1. all basic slice-flip-slice cases (including the double midge flip)
2. r U2 r U2 F2 r F2 l' U2 l U2 r2 (execute as r U2 r U2 x U2 r U2 3r' U2 3r B2 r2)
3. r2 F2 U2 r2 U2 F2 r2 (looks like PLL parity)
4. (F U' R U') (r2 F2 U2 r2 U2 F2 r2) (this case is missing from many alg sheets, including Speed Cube DB at the time of writing (!))
5. r U2 r2 U2 r' U2 r U2 r' U2 r2 U2 r and the inverse (diag checkerboards; this is the only L2E case where the best alg happens to be rU 2-gen)
6. all of the rest

I used to solve the 5x5 by doing the 4x4 first (ignoring the middle slice) then solving the 3x3 (big corners) to get the edges. That would bring me to the attached photo where I had a technique to swap the center edges until they were complete, finally solving the 3x3 with big centers to finish. That was years ago and I’ve forgotten what technique I used - muscle memory is giving me: u M u’ M’ after rotating the outer slices to get the configuration I want but of course that algorithm messes with all the centers so even if I get one right the others are screwed up. Does anyone have a suggestion? All of the center fixes I can find are for before the edges are done.

It is much better and faster to solve the centers before the edges on big cubes. The only real exception is the Yau method and even then, that's just a few edges, not all of them.

not to pat my own back, but there is a new method for solving big cubes, and it undoes parity and eliminates memorizing algorithms. it is https://www.speedsolving.com/wiki/index.php/ABCube_Method it is not great for speedcubing, but excels at large cubes, it does the centers last because the parities can be erased by a simple center slice turn,
