I thought anti-Sune was the variant I do use, R' U2 R U R' U R.

AFAIK it's right-hand "back anti-sune", regular (right-hand) sune is R U R' U R U2 R', and it's anti- version is R U2 R' U' R U' R' (reverse alg in fact).

If I understand correctly, in case of regular sune case I can do regular alg, or U+left-hand anti-sune, or U2+left-hand back-sune, or U'+back anti-sune. ;)

I don’t mind f-perms. I can execute those as fast as any PLL. It’s the N and G perms that give me the most issue.

Have you had a look back at that solve?

A four move xcross which you then broke up (because you didn’t know it was solved?)

Haha, that kind of thing must happen to me all the time because I don’t bother to use my inspection properly. And yet I never even thought about this until I just replayed your solution.

This could be used as the perfect example of why you should plan your first pair in inspection but I’ve never seen it mentioned anywhere.

It was a strange case because the orange green pair is together at the start, gets split up but then ends up together again in the most unlikely manner (if it was accidental)

And yet it would have been relatively easy to track I guess.

I’m going to really try to plan first pair for every solve in future. Despite starting yesterday with this intention, I reverted to type and just planned cross for most solves.

More discipline needed... this example has inspired me.

I hope.

First off: I was really happy I could reconstruct it at all, scrambling + my weird dyslexia means a lot of mis-scrambles unless I'm slow and pay really close attention.

It's double-ly embarrassing because I didn't notice the xcross during the solve nor while doing the reconstruction. Even if I had seen the pair it's likely I wouldn't have changed the solve anyway. I don't immediately see how to preserve it while solving the cross and my past experience is that trying to preserve a pair during cross costs me more time than ignoring it. So I tend to have blinders on for anything but my cross edges, saw a fairly easy 4-move cross here, and likely took off after 4-5 seconds of inspection (the orange/green pair at the end was unplanned luck).

Maybe I need a block-building crash course or something to develop an intuition for preserving pairs during cross, I'll gladly bookmark any good resources anyone has on the topic. As it stands I can't even X-Cross when given one unless it's super easy and obvious.

That's 3rd and 4th pairs solution is just incredible. My current skill is to solve only pair by pair ;)

Mostly pure luck. I rotated for the insert of the red/green pair knowing new information would be coming out of that back slot, so after the rotation I peeked at that corner coming out. I saw it indeed made the final pair for me, and with orange on top that meant I was already oriented for the last pair insert as well. I was a little proud to have the presence of mind to execute the L2 on the 3rd pair insert but I can't take any credit for the two gift pairs, themselves lol.
 
On the x-cross topic again... I don't have the tools to see how to preserve the made pair easily, much less in 4 moves. I'm sure I'll head-desk as soon as someone shows me the trick, the scramble again: B' D2 L2 F' D2 L2 U2 F2 R2 B D' L2 B U R F L2 U' L U2

I just actually looked at your solve. If you hadn't gone for OCLL but just used the OLL I use, you would have finished with:
U R' F' L F R F' L' F // AUF OLL
U2 T perm
Which I assume would have been a good bit faster.

Just in case there's confusion with COLL here: OCLL are just the seven OLLs with edges already oriented, so that's my normal OLL alg for that case and one of the oldest ones in my toolbelt since OCLLs were the first ones I learned (and it's a fairly fast one for me, basically being sexy-sledge but with a couple wide moves).

T-Perm would have definitely been preferable, regardless :D.

Wide moves generally create a mental block for me, so I use them for very few algs. I do use some, but they're often the ones I can't remember. :-( So that's why I learned this one instead.

I just did 3x3x3 for the weekly competition this week and got a 19.14 average. My average in the weekly competition for the past 10 weeks or so has been hovering right around 20 seconds. Which is wild, because I've never been globally sub-20, and I haven't explicitly practiced 3x3x3 in ages. Last time I made a conscious effort to practice it, it seemed like my average barely moved, and after a few weeks of stopping practicing, it got much worse. But now all of a sudden it seems like it might be better than it's ever been.

I'm definitely not planning on practicing 3x3x3 any time soon! :-)

I guess a possibility is that I might be improving by doing all 3 attempts of fewest moves every week. I do wonder if that's what's making the difference - I think it really can help regular 3x3x3 solving.

I swear this hobby can lead a fella into being as superstitious as baseball players, who knows :D

My current thing is it seems like I hit my zone when I'm listening to a Podcast or watching something streaming that doesn't require a whole lot of direct viewing attention, the supposition being that occupying the thinking part of my brain keeps me from over-thinking; don't think, just solve. But it's also how I do the bulk of my spam practice, so of course that situation has statistics on it's side.

Having reread my post, I perhaps did not express myself very clearly.

I didn’t mean you should do anything differently when making the cross.

But have you noticed that the four moves you did to make the cross also solved the green orange pair in the back?

You did a four move xcross!

However, you seemed unaware of this because you then proceeded to remove said pair, when solving what you considered to be your first pair.

My further musings are only that it if you go back and have a look from the start it is interesting to see the manner in which the green orange pair splits up then rejoins as you made your first four moves.

What I learnt was that it’s not so much about thinking about how to “preserve” the pair (for it wasn’t preserved, it split up then joined together again) but...

If you tracked the pair in your mind (edge and corner independently) as you planned your cross, you would have been aware that an xcross would form.

All the best YouTube teachers recommend infinite inspection time to plan first pair in inspection until you can get this down to 15 secs. This area is my biggest weakness so I’m trying to focus on it right now...

I’m not sure I have the discipline to do this... anyway, happy cubing

You're already did it.

R' F B' D // Cross - XCross really, orange-green pair is already in RB slot.

UPD. May be this is exotic and hard to imagine during inspection, but xxcross is possible too (with keyhole):
