Totally agreeing with the problems with rws too, although sometimes it does balance the teams, I see most of the matches today, one team is always getting destroyed.

The RWS balancing is somewhat successful. ~2/3 of pugs end with a score of at least 09-16 or better. A few years ago, I compared ADR vs RWS in predicting the final PUG's score and ADR was less accurate. A review of a couple of blowouts suggest they are caused by high RWS people leaving or joining teams. Another big factor is the map.

15-15  8.4%  (887/10508)
14-16  9.4%  (993/10508)
13-16  9.3%  (976/10508)
12-16  9.4%  (988/10508)
11-16  9.0%  (944/10508)
10-16  8.6%  (900/10508)
09-16  8.2%  (863/10508)
08-16  7.5%  (792/10508)
07-16  7.1%  (749/10508)
06-16  6.3%  (665/10508)
05-16  5.4%  (567/10508)
04-16  4.1%  (435/10508)
03-16  3.2%  (336/10508)
02-16  2.2%  (230/10508)
01-16  0.9%  (097/10508)
00-16  0.2%  (024/10508)

But keep in mind, that the teams in those pugs were made based on RWS, so just taking adr instead to see if its more accurate when the teams are made with RWS and not adr, certainly gonna show RWS being more accurate, they aren't made using adr ...

But yeah i agree on what you said, high RWS players are a bit unpredictable, meaning RWS or ADR being used doesnt really matter, even more if they leave or join out of nowhere to stack teams up.

Also keep in mind that there is always leavers/multiples subs, in every pug, so if the score ends up between 15-15 or 16-8 doesnt mean RWS is doing it job, those subs, except if a high rws leaves, balance the score most of the time, the teams made at the beginning with rws are often 100% unfair before subs evens them out.
