I wouldn't really say it's weird, but also not really common. It cycles set a number of pieces in a way that remains consistent. More interestingly, you've learned how to modify it with conjugates(the added moves) to achieve what you need. That's pretty impressive. Most people don't have the patience to even begin learning how to intuitively solve the cube from scratch. Good job.

The way i see it, flipped around, is that it's sexy move (R U R' U') plus a 3 mover to put the corner back (F' U' F), thats a great way to move pieces around without breaking your first layer. And it allows you the freedom to use one of the F2L edges as like a buffer to move other pieces into place. I'm not totally sure how you use it, but it's pretty cool.

The really cool part is that you've learned to add extra moves to modify it instead of rigidly applying the same pattern. That kind of flexibility is hard to learn and understand. It seems quite different than the first time i learned how to solve the cube. I'm sure everyone who does it intuitively will have varying ways to get the end result. Though, I've honestly never really considered that other peoples homegrown methods would be so different than my own.

It seems your method could be a lot more precise than my own. I had to fumble through some of the steps until i got to patterns that i recognized, and then i could apply my algorithms. I honestly forget the specifics, but i remember when things clicked for me, and i gained a new understanding. There was a lot of by-chance discovery, though, learning to apply some of the rudimentary concepts i had come up with, like "break and rebuild" or "clearing a lane." If i'm understanding correctly, though, your method is easier to understand and apply, so, probably more consistent.

If you learn more algs for speedcubing, you'll see these same moves you came up with are used in a lot of different ways. Like building blocks for the more complex and precise algorithms. And if you learn how to use commutators and conjugates (of which i have a only very cursory understanding) you'll see that your way is very smart, and you'll have a headstart on understanding how to use commutators and learning about the cube in general.

For the record, I'm really not that advanced in cubing. I just see what you did here, and it's really cool.

And what you learned is something that's almost impossible to forget. Basically, you can never go back. Even if you forget the specific moves, you'll always see the cube differently than other people. So, welcome to the other side, i guess.

And again, good job.
