The use of the game controller, Excel, etc. all goes to document a pattern of cutting corners. True, these corners are tiny compared to the issues of the overall design of the sub, but it demonstrates a long pattern of overall behavior.
This reminds me a bit of when I was a juror on a criminal trial. The prosecutor detailed a long string of seemingly small/inconsequential things that ultimately helped demonstrate a long pattern of behavior. That pattern definitely helped with our deliberations.
I’d be more concerned if it had flown away.
