Life In 19x19

We have been debating about ways to measure improvement over time.

Does anyone care to opine on these two KGS rating graphs?

I think they are basically flat over the past year. One (jingo) is fairly stable (y-axis is 4k-1d) while the other had a really strange drop to 8k at the end of last year ...

My son has been frustrated recently with several loses. I'm not strong enough to helpfully review, so any comments are appreciated. In this game, we are mostly interested in advice for black, but thoughts about white's play are also interesting.

white makes several mistakes and, I feel, is behind through most of the game, then wins on time at the end (equivalent to a resignation?)
I'd appreciate comments on mistakes (esp for white).

Now, I still can't get most of the wbaduk functionality to work, but at least I have a registered account now...

I'm struggling at an even earlier stage: can't register on the site. I get a registration key code, but when I enter it, wbaduk just gives me a pop-up error that the code was invalid. I feel bad because I (inwardly, at least) was mocking my wife for not being able to figure out how to set up an ...

Another camp league match. Unfortunately, I deleted most of the game record and my opponent didn't continue recording after his group on the bottom right died.

5 stone handicap.

I don't think so.

This is an on-going game. Probably not interesting to anyone other than the current players.

Is there a list of all the "ranks" for posters on L19? I've seen:
beginner
dies in gote
dies with sente (probably worse than lives in gote, but depends on board situation?)
lives in gote
lives with ko
lives in sente
shodan
judan
tengen
oza
gosei

I've listed in the order I guess the run from someone ...

another recent game. I am going to review this with someone offline, so no need to comment. I just wanted to have it easily accessible.

Game from this weekend, part of the AGHS young lions tournament.
I would be curious to hear feedback about how you respond to such an aggressive opponent.
FWIW, the two players are friends who met at the AGA youth summer camp this July, but they haven't played each other since then.
