A comprehensive list of non-algorithmic pairings in RLCS 2021-22 Fall Split

Don’t read this post by accident.  It’s just a data dump.

This is a list of every Swiss scoregroup in RLCS 2021-22 Fall Split that doesn’t follow the “highest seed vs lowest possible seed without rematches” pairing algorithm.

I’ll grade every round as correct, WTFBBQ (the basic “rank teams, highest-lowest” would have worked, but we got something else, or we got literally impossible pairing like two teams who started 1-0 playing in R3 mid, or the pairings are otherwise utter nonsense), pairwise swap fail (e.g if 1 has played 8, swapping to 1-7 and 2-8 would work, but we got something worse), and complicated fails for things that aren’t resolved with one or more independent pairwise swaps.

Everything is hand-checked through Liquipedia.

There’s one common pairwise error that keeps popping up, with 6 teams and the #2 and #5 (referred to as 7-10 and 10-13 error a few times) have played.  Instead of leaving the 1-6 matchup alone and going to 2-4 and 3-5, they mess with the 1-6 and do 1-5, 2-6, 3-4.  The higher seed has priority for being left alone, and EU, which uses a sheet and made no mistakes all split, handled this correctly in both Regional 2 Closed R5 and Regional 3 Closed R4 Low.  EU is right.  The 7-10 and 10-13 errors below are actual mistakes.

SAM Fall Split Scoregroup Pairing Mistakes:

Invitational Qualifier

https://liquipedia.net/rocketleague/Rocket_League_Championship_Series/2021-22/Fall/South_America/1/Invitational_Qualifier

Round 2 High, FUR should be playing the worst 3-2 (TIME), but is playing Ins instead. WTFBBQ

Round 2 Low, NBL (highest 2-3) should be playing the worst 0-3 (FNG), but isn’t. WTFBBQ

Round 3 Low, Seeding is (W, L, GD, initial seed, followed by opponents each round if relevant)
13 lvi     0 2 -3 3
14 vprs 0 2 -4 12
15 neo  0 2 -4 15
16 fng   0 2 -5 16

but pairings were LVI-NEO and VPRS-FNG. WTFBBQ

Round 4 high:

Seedings were (1 and 2 are the 3-0s that have qualified, not a bug, the order is correct- LOC is 2 (4) because it started 2-0)
3 ts 2 1 4 5 vprs time fur
4 loc 2 1 1 14 lvi tts era
5 nbl 2 1 4 4 time vprs ins
6 tts 2 1 2 11 elv loc kru
7 elv 2 1 1 6 tts lvi nva
8 time 2 1 0 13 nbl ts dre

TS and time can’t play again, but 3-7 and 4-8 (and 5-6) is fine. Pairwise Swap fail.

Round 4 Low:

9 nva 1 2 -1 7 kru era elv
10 dre 1 2 -1 9 ins fng time
11 ins 1 2 -4 8 dre fur nbl
12 kru 1 2 -4 10 nva neo tts
13 lvi 1 2 -2 3 loc elv neo
14 vprs 1 2 -3 12 ts nbl fng

All base pairings worked, but we got ins-lvi somehow. WTFBBQ

Round 5:
Seedings were:
ts 2 2 1 5 vprs time fur elv
time 2 2 -2 13 nbl ts dre tts
loc 2 2 -2 14 lvi tts era nbl
lvi 2 2 -1 3 loc elv neo ins
vprs 2 2 -1 12 ts nbl fng nva
kru 2 2 -2 10 nva neo tts dre

Loc-LVI is the only problem, but the pairwise swap to time-lvi and loc-vprs works fine. Instead we got ts-lvi. Pairwise swap fail (being generous).

4 WTFBBQ, 2 pairwise swap fails, 6 total.

SAM regional 1 Closed Qualifier

https://liquipedia.net/rocketleague/Rocket_League_Championship_Series/2021-22/Fall/South_America/1/Closed_Qualifier

Round 2 High has Kru-NEO and Round 2 Low has AC-QSHW which are both obviously wrong. WTFBBQ x2

Round 3 High

1 ts 2 0 6 1
2 ins 2 0 5 6
3 dre 2 0 4 4
4 neo 2 0 4 7

And we got ts-dre and neo-ins WTFBBQ

R3 Mid
5 nva 1 1 2 5 emt7 dre
6 loc 1 1 1 3 naiz ins
7 kru 1 1 -1 2 qshw neo
8 fng 1 1 -2 8 lgc ts
9 lgc 1 1 2 9 fng prds
10 ac 1 1 2 10 neo qshw
11 bnd 1 1 0 11 ins naiz
12 emt7 1 1 0 12 nva nice

5-12 and 8-9 are problems, but the two pairwise swaps (11 for 12 and 10 for 9) work. Instead we got nva-bnd and then loc-ac for no apparent reason. Pairwise swap fail.

Round 3 Low:
qshw 0 2 -5 15
nice 0 2 -6 13
naiz 0 2 -6 14
prds 0 2 -6 16

and we got qshw-naiz. WTFBBQ.

R4 High:
dre 2 1 1 4 nice nva ts
neo 2 1 1 7 ac kru ins
nva 2 1 5 5 emt7 dre bnd
ac 2 1 3 10 neo qshw loc
kru 2 1 0 2 qshw neo lgc
fng 2 1 -1 8 lgc ts emt7

neo is the problem, having played ac and kru. Dre-fng can be paired without a forced rematch, which is what the algorithm says to do, and we didn’t get it. Complicated fail

R4 Low
9 lgc 1 2 1 9 fng prds kru
10 loc 1 2 0 3 naiz ins ac
11 emt7 1 2 -1 12 nva nice fng
12 bnd 1 2 -3 11 ins naiz nva
13 naiz 1 2 -4 14 loc bnd qshw
14 prds 1 2 -5 16 ts lgc nice

9-14 and 10-13 are rematches, but the pairwise swap solves it. Instead we got EMT7-PRDS. Pairwise swap fail.

R5:
6 neo 2 2 0 7 ac kru ins fng
7 ac 2 2 0 10 neo qshw loc nva
8 kru 2 2 -2 2 qshw neo lgc dre
9 lgc 2 2 4 9 fng prds kru naiz
10 loc 2 2 3 3 naiz ins ac prds
11 emt7 2 2 2 12 nva nice fng bnd

7-10 and 8-9 are the problem, but instead of pairwise swapping, we got neo-lgc. Really should be a WTFBBQ, but a pairwise fail.

+4 WTFBBQ (8), +3 Pairwise (5), +1 complicated (1), 14 total.

Round 2 Low:

FDOM (0) vs END (-1) is obviously wrong. WTFBBQ. And LOLOLOL one more time at zero-game-differential forfeits.

R3 Mid:
5 fng 1 1 2 4 nice loc

10 sac 1 1 0 16 vprs flip
11 end 1 1 -1 11 loc emt7
12 ball 1 1 -1 15 nva nice

The base pairings work, but we got FNG-end and ftw-ball for some reason. WTFBBQ. Even scoring the forfeit 0-3 doesn’t fix this.

R3 Low:
emt7 0 2 0 8
flip 0 2 -5 10
nice 0 2 -5 13
ac 0 2 -6 12

and we got emt-flip. WTFBBQ.

R4 High:

fng, the top seed, doesn’t play either of the teams that were 0-2.. base pairings would have worked. WTFBBQ.

end-tn doesn’t work, but the pairwise swap is fine, and instead we got end-fng!??! Pairwise fail.

14 sac 1 2 -4 12 lev emt7 resi

9-14 and 10-13 are problems, but the pairwise swap is fine.  Instead we got emt7-ftw which is stunningly wrong.  Pairwise fail.

Round 5:

6 fng 2 2 -2 6 ball resi endless endgame
7 bnd 2 2 -2 16 endgame benz ball lev
8 tn 2 2 -3 2 benz endgame ftw fdom
9 ftw 2 2 1 7 fdom ag tn emt7
10 endless 2 2 0 8 emt7 lev fng ag

This is a mess, going to the 8th most preferable pairing before finding no rematches, and.. they got it right.  After screwing up both simple R4s.
