Oxford Memo Tutorial | Rethinking 7-Simul

Oxford is a different system of 7-simul memo developed by me and Caleb Trelford in which you don't calculate the moves you will apply with each hands, but rather the positions you will put certain "reference clocks" in. The idea is that this will help prevent "counting" moves or calculating the target position in your head during the solve; instead, it is all accounted for in the calculations themselves.
CALCULATIONS:
1a [DL]. c-d + DL
1b [D]. (D-L+U) + (dr-r)
2a [DL]. 1a + d-r OR c-r + DL
2b [D]. 1b + L-U OR D + dr-r
4a [L]. C-D+l-ul + NP*
4b [DL]. u-ul + DR-R + NP
*Be careful about Noon Position with 4a when noon is on top or bottom; Noon Position is determined on the EXECUTION side, so keep that in mind when account for NP at the end of your 4a calculation, since 4a ends on the lowercase side.

You are a genius, you have to be a genius to think of this

some counterarguments just so people have a full picture: (for context, I was the only non-Dylan person to practice seriously with oxford when the method was first developed and I wasn't convinced it was better than regular 7sim; for more context I averaged low 4 with regular 7sim at the time): 1. The biggest issue I had with oxford is with non-obvious skips being even less obvious. In regular 7sim, when you get 0 as one of your memorised numbers you know there's a skip coming and you can mentally prep for it to avoid awkward pauses. (For 4/6 numbers that you memorise in 7sim you can't tell whether there's a skip without actually doing a calculation - hence "non obvious skips") - but you know as soon as you do the calculation, if it's 0, it's a skip. In Oxford, the skip won't show up as 0, it could show up as any number. You have to do the extra mental work of realising the reference clock is already at your memorised position and then you know there's a skip. Dylan tries to avoid this by looking ahead but knowing instantly that there are skips seems meaningfully better to me - instead of having to do extra work to realise that at the end of inspection or even mid-solve. 2. I'm really not convinced that the mental calculation people do (what Dylan discusses at 6:00) is meaningful - for me it feels practically instant with no real thinking involved, so it doesn't feel like an advantage gained by Oxford. 3. The "visual" style of turning (6:25 in the video) is (in my opinion) significantly easier for flip solvers (or for the intuitive 7sim moves) than for Oxford - this is because the visual stimuli they're basing their decisions on is just significantly bigger (for oxford it is a relatively tiny marking on one specific clock; for flip/for the intuitive 7sim moves it is another clock itself, or a group of clocks, which your brain can process with much less focus) - so I'm not convinced at all that the transition between "visual" and "calculated" moves is removed by oxford. We actually found Dylan had a larger % of his solve time in the pause between \ and UL - where the calculated moves end and intuitive moves begin - when compared with Niklas, suggesting that there's a mental break period between calculated and intuitive moves for him. Keep in mind this is a sample size of 1 person, so this could just be Dylan having a skill issue as opposed to an Oxford issue. My final conclusion was that the significantly easier memo (and easier accuracy assuming you memo correctly) made Oxford a little like the Lin method for square-1: more beginner friendly, easier to get fast, but probably harder to get world class. I believe it's easier to get sub 5 with oxford, but it's harder to get sub 4.

if only I knew someone who could tell me what the optimal memo is

It’s nice how the reference clocks are near each other so you don’t have to look at separate parts of the clock while doing simultaneous moves.

This is what's kept me from 7simul. My skillset with Sheeran has been turning both arrows to a certain position, not by doing x move. Thanks!

I think the is why I struggled with actually doing the moves simultaneously is because I was counting during the solve :0

have you applied this idea to any other pin sets yet?

@OxzowachiAlt 7 ай бұрын

yes, I have tried this with a handful of different pin orders, as well as with different reference clocks. you can find all of these here docs.google.com/spreadsheets/d/1BEBsT-NKqng8GMsEyq0N_xjKMqFJzgV1nfP0cLxl-Go/edit?usp=drivesdk
