Is there an algorithm to behavior score?

I was sitting comfy on 11k behavior score until I had to abandon a game. According to steam dota hidden data I got 2 reports for griefing in the same match. (Didn’t grief, I was winning hard for the team but family emergency called. I understand people get mad at abandons.)

This dropped me to 9600 behavior score.

What would scientifically be the quickest way to get back to 11k? Is it possible in two conduct summaries?

Assume I play 30 turbo matches and that i receive 0 reports and 2-3 commends in each and every one of those 15 turbo matches. What would the net gain of behavior score be?

Are there hidden algorithms to the score? Is there anyone who has access to the exact code of how behavior score works number by number?
