40/40/20 is fake

i am held back by my botlanes every game, which is the easiest role. i tested this 40/40/20 theory in 10 games. i concluded, it's fake, i won 30 percent by default, lost 50 percent by default, and 20 percent was other. out of the 5 default loses my botlane averaged a score of 1/12/3. from that i can conclude riots matchmaking is terrible.
