 When we take a closer at the graphs of 55, 75 and 85 gates and draw a regression line through it, something else becomes clear.

 ## Conclusions
 
-Within the scope of our experiment and by the data we were able to produce, we can say that the score function increases linearly with the length of a netlist. There are two possible explanations for this phenomenon:
+Within the scope of our experiment and by the data we were able to produce, we can say that the score function **does not increase linearly** with the length of a netlist. There are two possible explanations for this phenomenon:
 1. The written program always produces the best score for a netlist (which has the shortest possible paths, so the score is only depending on the amount of paths that is drawn)
-2. The score function has a simple nature. If it contained more variables, it could be that the score function behaves differently.

 ## Discussion
 
 After completing this experiment, we found some ways to improve and extend this experiment in the future:
-1. Increase the scope of the experiment by generating netlists with a length of 50 and up. This can be used to verify or disprove the credibility of this experiment.
+1. Increase the scope of the experiment by generating netlists with a length of 50 and up. This can be used to see how the curve behaves beyond the tested perspective, so we can verify or disprove the credibility of this experiment.
 2. Find a way to shorten the runtime of the program (runXX.py) to generate results faster.
 3. Save more data of every solution than purely the score of the board. For example:
