More small tweaks, perf from 77.. to 75.., another 2-3%?

Added some options in the prepare file, makes a small difference, also tweaked the code to eliminate even more cycles.

Check List:

• [X] Tests pass (./test.sh <username> shows no differences between expected and actual outputs)
• [X] All formatting changes by the build are committed
• [X] Your launch script is named calculate_average_<username>.sh (make sure to match casing of your GH user name) and is executable
• [X] Output matches that of calculate_average_baseline.sh

Ah strange, “worked on my machine”.

I’ll update the PR tomorrow with more lenient settings and some small tweaks.
