Crap now I need to get 5 solves instead of 3 for the profile :/

 

[CornerCutter]

Why is this better? It will just make the event take longer.

Because if you dnf or have a bad solve it doesn’t screw you over

 

[DGCubes]

Yes! Definitely a major win for us feet solvers!

 

[Kit Clement]

Well, it hasn't been changed yet -- this is still pending board approval.

 

[GenTheSnail]

YESSSSS

I didn't realise there was a demand for feet Ao5s, in fact I always thought it was pretty unpopular.

Would've loved to have seen 4BLD/5BLD means being recognised instead as it requires even less work from the software team, regulations team and comp organisers' to implement (in my biased opinion.)

This also suggests that feet isn't likely to be removed any time soon.

Meh.

Some analysis - there seem to be more distinct WCA competitors competing in feet compared to 4BLD and 5BLD. The number of competitions holding feet year-on-year is similar too.

Spoiler: R code

library(data.table) # install.packages("data.table")

# Load in the data from the 02-Nov-2017 export.
results <- fread("C:/OF/WCA_export011_20171102/WCA_export_Results.tsv", select = c("competitionId","eventId","personId"))
comps <- fread("C:/OF/WCA_export011_20171102/WCA_export_Competitions.tsv", select = c("id", "year"))

# Perform joins and filter.
results <- unique(results[eventId %in% c("333ft","444bf","555bf")])
merged <- merge(x = results, y = comps, by.x = "competitionId", by.y = "id")

fourbld <- merged[eventId == "444bf"]
fivebld <- merged[eventId == "555bf"]
feet <- merged[eventId == "333ft"]

# Unique competitors by year.
ftable(fourbld$year)
ftable(fivebld$year)
ftable(feet$year)

# Number of competitions holding these events year on year.
comps_fourbld <- unique(fourbld[, c("competitionId", "year")])
comps_fivebld <- unique(fivebld[, c("competitionId", "year")])
comps_feet <- unique(feet[, c("competitionId", "year")])

ftable(comps_fourbld$year)
ftable(comps_fivebld$year)
ftable(comps_feet$year)

Doesn't really say much though - I have no idea if there was a drive for feet ao5s to be added.

 

[TheCoolMinxer]

yeah, now I will always have 2 bad solves which ruin my avg instead of 1 bad solve lol.
but seriously, I am really happy with this change!

 

[Ollie]

Edit: realised today it's popular in other countries.

I find this very interesting...

 

[DGCubes]

Does this mean that mini Guildford will include feet now (assuming the changes go through)? Will all previous mini Guildford UWRs be invalidated?

 

[Ranzha]

I'd just consider a "Classing Guildford" and a "2018 Guildford" if the changes are made

Maybe keep mini as it is and make a medium Guildford for feet? and rename normal Guildford to Large Guildford.

 

[asacuber]

woaj inspecting with hands is something i need

I think it's just easier to invalidate the UWRs, the new names would drive me crazy lol.

When blind and FMC means were made official the Guildford challenge remained the same.

 

[DGCubes]

When blind and FMC means were made official the Guildford challenge remained the same.

They changed when Skewb was added though. (Although, Skewb is a lot easier to throw in because it's short and not too different from the pre-existing Guildford events.) Personally, I think the definition of the Mini Guildford challenge (all events with an average of 5) should stay the same, so feet should be added; otherwise it just seems like an arbitrary list of WCA events.

I can't find it right off, but I remember hearing that Feet would be reevaluated after some time on the basis of how the switch to Ao5 affected participation. Out of curiosity, here are a few stats about the number of people completing official feet singles, and expressed as a percentage of people with 3x3 singles in the same time and region.

2016 World: 629 (2.385%)
2017 World: 877 (2.447%)
2018 (ytd) World: 713 (2.507%)

2016 Africa: 7 (1.659%)
2017 Africa: 10 (3.610%)
2018 (ytd) Africa: 6 (1.852%)

2016 Asia: 219 (2.402%)
2017 Asia: 336 (2.314%)
2018 (ytd) Asia: 207 (1.998%)

2016 Europe: 205 (3.588%)
2017 Europe: 277 (3.676%)
2018 (ytd) Europe: 207 (3.033%)

2016 North America: 127 (1.702%)
2017 North America: 180 (2.022%)
2018 (ytd) North America: 225 (2.900%)

2016 Oceania: 6 (0.902%)
2017 Oceania: 7 (0.920%)
2018 (ytd) Oceania: 7 (1.124%)

2016 South America: 65 (2.175%)
2017 South America: 67 (1.742%)
2018 (ytd) South America: 61 (2.389%)

About time to do it for 3BLD, it will be so better if 3BLD is converted to Best of 3/Best of 5 format.
https://github.com/thewca/wca-regulations/issues/571

Sebastiano Tronto has already pointed out its feasibility!
