What happens actually depends on the odds for 0-0 at kickoff. For the example you've given where 0-0 starts at 10, if the score is still 0-0 after 10 mins, then 0-0 would move to about 7.7, both 1-0 and 1-1 also generally move lower. It is the higher scores (those with total goals of 3 or more) that move higher.

I hope this helps you.
