Salt Cat: Mad Handicap 9x9

Second round complete.
471 games, 99 timeouts.

image

Outcome was quite balanced for 0 and 1 handicap
Even with 4 ranks difference, there were 16 vs 12 games, 57 vs 43 %.
Groups with 2 and 3 handicaps saw more black wins, but the number of games wasn’t so large and stats couldn’t be reliiable.

Third round has 420 games.
We go up to 4 handicap with 5.5 negative komi.

Handicap should be calculated from new ranks, I suppose.
I had to switch from v1 API to termination-api for the players list, since the former had broken rankings.
I didn’t do the same yet for games, so I am still retrieving games data from v1 API.
I actually don’t know where to look for starting ranks.

I used to look in v1 “gamedata” section but it doesn’t appear updated with new rankings. Example:

    "gamedata": {

        "players": {

Now “historical ratings” section looks the most updated. Maybe I should use that one, but I would be grateful for every possible hint or help about it, since I feel quite lost.

I also checked termination-api but it looks even worse:

<https://online-go.com/termination-api/game/31277608>

"white_player_id":308797,
"black_player_id":11184,
"game_id":31277608,
"game_name":"Tournament Game: Salt Cat: Mad Handicap 9x9 (66295) R:3 (Lys vs zhal)",
"players":
	{"black":
		{"username":"zhal",
		"rank":18.35705953107835,
		"professional":false,
		"id":11184}	,
	"white":
		{"username":"Lys",
		"rank":21.308412146517206,
		"professional":false,
		"id":308797}},
	"handicap":1,
	"komi":3.5,

I removed many lines which were useless for my goal.
Anyway, according to termination-api players seem to be still 12k and 9k, while these are our mugshots today:

@benjito, can you dig something here?
