efficiency and safety strategy based on the position?

[asd62033]

Is that possible to set the safety and performance factor in different situation?
For instance, leading in first position in South 3~4 can play much more safer or low value tenpai ;
or play much more aggressive and bigger value hand when behind.
The reason I have this thought is because of the situation that I saw: AI will play 1000 value ron even when you in 4th position at All Last or try to a risky tenpai when you are first position.
