[Help Thread] Multi-Blind Discussion

[Christopher Cabrera]

I perfectly understand what you mean. Especially 2) showed my logic was far from perfection. Yet, I still insist on 2 things: 1. Time should be counted as a factor of scoring. 2. With current rules, penalties with unsolved cubes are a little too harsh.
From that, I've tweaked my formula a little bit:

((Number of solved cubes)-(Number of unsolved cubes)*x)/(Time (in hour))^y

Both x and y are constants that I'm unsure about their appropriate value, but I think x should be around 0.5~0.8 (to soften the penalty) and y be around 0.1~0.3 (to apply weaker 'speed bonus'). This should make the formula more moderate.

And to be honest, I'm a total MBLD noob - my PB is only 2/2 in 9:39. I've started to think if posting my idea was a mistake at the first place since I do not know very well about the event...

Time should not be a heavy factor in scoring because like I said before multi blind is different from all the other events. The goal of a multi blind is not to find out "Who's the fastest," It is to figure out who has the abiltity to memorize and exectute more cubes in under an hour. It's a bit like the reason we do not include time factors for FMC. Furthermore, by this metric someone who has the ability to memorize and execute 11 cubes is more "skilled" than someone who has the ablity to memorize and exectute 10 cubes, regardless of time. If you are at the point where you solve 10/10 in 30:00 and you are upset because some one else beat you by doing 11/11 in 60:00, the problem is not with the scoring system. The problem is that you are not pushing yourself hard enough

While I like the idea at a first glance, it's important to keep in mind that MBLD is,differently from 3BLD, not about solving one cube really fast, but about solving (as) many cubes (as you can) consistently.

My first 7 cube attempt got 5/7 (49:22)

Spoiler: Mistakes Made

I forgot to memo a flipped edge on one cube ans apparently forgot to execute one cycle on a different cube

All in all it was better than I expected. I'm hoping to try for 9/9 by the end of the month so I believe I am on a decent pace

23/25 MBLD in 59min 20.44s, finally sub1hr!

Execution mess ups for one cube and forgetting a flipped edge for the other

2) Points are determined by (number of solved cubes)-(number of unsolved cubes), not number of solved cubes only
I know this could be kind of controversial, but to me being penaltied by unfinished cubes seems to be unfair. For example, why should 5/10 attempt counted as 0 point and then DNFed when the competitor succesfully solved 5 cubes? He/She did complete exactly same amount of cubes with the one who did 5/5, but the result is nothing but DNF only because of the rest of the cubes, remaining unsolved. That's kinda nonsensical, I should say.

There's a very big difference between someone who can do 5/5 cubes with perfect accuracy vs someone who gets 10 scrambles but just solves the 5 easiest ones. Accuracy has to pay a role in how the scoring works to distinguish between these situations.

I just realised that this is actually PB too

Beats my 21/21 MBLD in 59min 37.08s from Jan

Wow

 

[YouCubing]

6/7 in 35:24, PB first 7 cube attempt with the 7 qiyi sails i ordered
beats my old PB (5/5 in 43:53) by 8:29

on cam, I'll upload the video when I have enough time to let my computer upload for an hour

 

[CyanSandwich]

33/42 1:04:20.02[38:52.76]

6 of them were off by a 2-flip lmao. Execution PB for 42 cubes, but still quite slow.

I'll need to memo a bit faster and shave 4-5 seconds off execution per cube. Then there's the whole accuracy thing

Warming up in mbld after an extended break due to exams

20/20 in 29:04 [16:23]

Time has a lot of room for improvement but still happy with accuracy
My best attempt yet with all cubes sovled! Previous best was 15/15

I have just got an idea about "ranks" for MBLD

Cubes sub-hour/rank
1-9 = rookie
10-19 = intermediate
20-29 = PRO (Over 20 people in the world)
30-39 = GOD (About 5 people)
40+ = Maskow (1 person)

As for me, I am between intermediate and pro(my pb is 19/20 in 56:xx).

Is this a metric used to measure a person's ability in the event or is it just based on official results?

 

[Gregory Alekseev]

Yes, a metric used to measure ability in event. This is how I divide MBLDers. What do you mean by "based on official results"?

I'm pretty sure there are other multi BLDers who are capable of 40+ results Maskow is just the only one who has done it at competition.

Also my idea of ranking would look more like this:
1-5 = Rookie (People who just started the event)
6-12 = Intermediate (People who actually practice this event)
13-20 = Aficionado (People who likely main BLD events)
20-30 = Pro (People who will likely win/podium at most competitions)
30+ = World Class (People who would likely win/podium at worlds or continental championships)

 

[lucarubik]

yh defenetly 9 cubes aint rookie

 

[FastCubeMaster]

Official 3/6 19:21 >.<
Heh, but I've got the WR for the fastest 3/6 attempt xD

DNFs were:

1: flipped edge
2: 2 twisted corners
3: asdfasdfasdfasdf idk what happened, probably I did some extra move or something.

xd the NR is 6/6 in 40something minutes lol, I went for that but failed like a pro

That should a DNF

23/25 MBLD in 1hr 30.07s

Roughly 40min memo and execution was very fast for me, so quite good

Soz for double post,

But how many 23/25s so you have?
Amazing mate

I have Two that are sub1hr

 

[FastCubeMaster]

I have Two that are sub1hr

What about with any time?
I just keep seeing those numbers

 

[lucarubik]

ikr

 

[kake123]

What about with any time?
I just keep seeing those numbers

I can't remember tbh

And looking through attempts that I have done about a month is very tedious

Edit:
Other 23/25 in chronological order backwards:
23/25 MBLD in 1hr 30.07s
23/25 in 1:04
23/25 MBLD in 1hr 6min 27.90s
23/25 MBLD in 1hr 20min 57.20s
