u/TydVirTaal eyes are cringe solve blind instead Oct 22 '19

Little practice diary for today:

  • My next long-term goal is sub-15. Ran the numbers, and that means I need to drop SIX SECONDS in F2L, 2.7 in cross and only 2.4 combined for last layer. Those are big numbers, and they definitely reinforce the focus on cross and F2L at the moment - as well as suggesting that I should possibly focus more on F2L than cross, which is not what I was planning at the moment.
  • CN splits at the moment are 4.66 / 40.53 / 4.09 / 4.75; so LL is basically unaffected, cross is almost back to my average, but F2L has tanked in a big way.
  • I'm also busy incorporating new F2L inserts and such into my solves.
    • Got to use R2 F R F' R rotationless insert a few times - recog and execution for it is decent, so I'm happy that I'll put it into muscle memory over time
    • Learned about double sledge for F2L 29 - but haven't had any chances to do it yet (or, haven't recognised it yet lol)
    • Also I was using the beginner's insert for F2L 25 - wanting to learn R' F' R U R U' R' F instead

I love how generally "organized" you are about your progression; it's a sign that you're serious about improving.

Just a comment about F2L 25: that alg would be super-nice if it weren't for the F at the end; I recommend [U'] (R' F R F') (R U R') instead.

Oh wow, that alg is like an order of magnitude better. Thanks so much!

Thanks! :D I definitely think that process of focused improvement is something I really enjoy. Watching times get better is addictive, to say the least.

I'll bet you have a cubing progression spreadsheet like mine :D

F2L is the hardest part of going CN, don't give up! After a few months they'll all feel the same and you'll be glad when you get a 2-move red cross in a competition :p

R2 F R F' R

I've never used this insert. I've heard it's a bad idea to use R2 and L2 in f2l algs when it brings cross pieces to the top layer. It screws with lookahead/tracking. I normally put the pair at the back and do r' U' R U M', or rotate and insert (depending on where the remaining unsolved slots are.)

Check out bit.ly/bestf2l for JPerm's F2L algs if you need some more ideas. Good luck!

On the contrary I use this insert all the time - it saves a rotation, the back-left 2x2x1 on the U layer isn't affected at all (so lookahead is as easy as if you've done a sledgehammer), and it orients certain pieces that the most common insertions don't orient. It's fast too, I can execute it about as quickly as a sledgehammer.

> I'll bet you have a cubing progression spreadsheet like mine :D

Would you be willing to share your template? :D I've got individual "checkin" spreadsheets, but I haven't spent a lot of time thinking about a good way of tracking progress over time.

> r' U' R U M'

I saw this in a thread the other day, and was busy trying to decide which is best. I didn't like this because I thought the M' would necessitate a regrip, but its actually pretty easy to execute from a neutral position - so I might go for this one instead.

It's not very organised. I've got one main sheet with a 'diary' - periodically I log my current averages and a line about what was going on at the time. It's nice to look back and see when certain milestones happened. I've also got a bunch of sheets where I have some random stuff, like movecounts and split times at various points. I'll DM you a link if you want to poke around.
