reduction parity on odd cubes vs even cubes

so I never understood why people prefer odd cubes vs even cubes.
they said odd cubes didn't have reduction parity.

now that I got all wca NxN and solved them a few times I understand.

in fact all big cubes have reduction parity, but as I see now, the difference is that on even cubes, you will normally see the parity when you are on last layer.
if you didn't do opa, you will encounter parity problems in the last layer.

for odd cubes, during edge pairing you will have parity, and you can solve it straight away, that's because parity don't affect midges, just like 3x3 edges. so it's noticiable during edge pairing.
and you won't have 2 edges swap like on even cubes.

so as I see odd cubes have reduction parity but it's easier to deal than even cubes, so no need for poll and ppll. yay

tl;dr - big even cubes: parody during LL if no opa. big odd cubes: no parody after reduction. I can't even

is that right?
 
if you learn all 12 of the Last 2 Edges (L2E) algorithns for 5×5 they also can be applied to resolve L2E on 6×6, 7×7 and up...
(I actually like it when that hits on bigger cubes ha)
...and one of the 12 IS the edge parity algorithm...

I recommend learning all 12 of them (some are sorta mirrors to eqch other) but you can get by pretty well with about 5-8 of them...
and also play around with it, a lot of times you can influence the L2E case with how you do Flip-Slice-Flip going through L4E.

*note* practice the Edge Flipping Algorithm and get it down good, you will use it a LOT... it will also help to practice and get good at doing it from different angles on the cube to help avoid rotations

anyway, what's really important is:
How come it's rHythm but not algorHithm??? ¯⁠\⁠(⁠°⁠_⁠o⁠)⁠/⁠¯

Yeah I'm gonna start learning the Algs asap
you can still get PLL parity I think

it seems I recall Cube Master has a pretty good video about the two parities you can get on 4×4 ... worth a watch
No, odd cubes midges have same rules of 3x3 edges so you wont get even cubes pll parity after reduction is done
also, check these out, lots of good info from the multiple times 6×6 & 7×7 WR holder Kevin Hays:

Nice um gonna take a look!

And since you realize that reduction parity occurs on all cube sizes, it's important to note that, should you be interested to find algorithms for big cube edges or centers, to not make the mistake of just testing them on even cubes . . . because even cubes are more "lenient". It's better to test them on, say, the 4x4x4 AND 5x5x5. (But it's better to test algs on the 6x6x6 and 7x7x7, because they are the smallest cube sizes to have "oblique"/arc center pieces.)

And to really take this idea of algorithms appearing different on different size cubes to a different level, whenever you have the time (and if you're interested), watch my video series derivation of my "Holy Grail" Single Parity (visually pure) algorithm from 2010. Specifically, Part 3 is the one I'm thinking about. But Parts 1-2 derive the algorithm that one needs to translate to higher order cubes (6x6x6 and larger) in Part 3, and so maybe you may be interested (especially since I derived the algorithm from scratch in those 2 videos). Part 4 is unnecessary for the topic at hand, but is necessary to at least understand the WHY of what I chose to do in Part 3. The last 2 videos in the series are related, but, again, not necessary for the topic on hand.
