Both. I did it manually until the Riot API came along, at which point I used it to build my own game database.
Some other stats from my database:
56.8% jungle with 53.8% winrate
20.9% top with 50.0% winrate
19.4% support with 48.15% winrate
1.8% ADC with 40% winrate
1.1% mid with 0% winrate
(Note that my role preference skews a lot of the other stats)
I've played 24 champions in ranked. When playing my top 10 champions, I have a 54.5% winrate. When playing the bottom 14 champions, I have a 27.8% winrate.
In 278 games, the top five most common champions on either side were Thresh, Jinx, Blitzcrank, Janna, and Graves. The top four least common were Singed, Zilean, Kindred, and Galio, each with only 2 games. (There is a six-way tie for fifth between Aatrox, Quinn, Elise, Kog'Maw, Skarner, Taric, and Twitch - 4 games each.)
When the other team has Leona, Amumu, or Orianna, I have a >75% winrate. When the other team has a Blitzcrank, Ahri, or Janna, I have a < 40% winrate.
The effect of globals on my winrate:

The stats most correlated with whether I won:
1) Riot Grade, correlation 0.73
2) DF, calculated as K*2 - D*3 + A, correlation 0.71
3) GPM, correlation 0.63
4) KDA, correlation 0.56
5) Deaths, correlation -0.55

So it's not something I'd be able to find retroactively
Also dat 0% mid winrate :p
