I suggest a penalty of 15 meters for Tracks 1&2.
When a low value is selected, the penalty does not have any significant effect.
On the other side, high penalty values tend to penalize accurate systems in excess.

Sorry, I cannot give my opinion for this point.

Due to the "indoor" nature of the competition, I consider that the third option may be the most appropriated one.
