The reason why the code failed to realize there was even an issue?...(in the case I mentioned earlier) The software looked at the calibration data using linear best fit (standard stuff) and provided the r^2 was within the specified range - that instrument and the data was good to go. Well, if you run your Standards{1,2,3,4,5} and all output "0.0". That is a straight (perfectly so) line. They had no idea how to read the computer monitor and the real time data coming off the instrument. They had zero real training / understanding of even how the instrument worked. I see this a lot still - people using an instrument without a great understanding of how the thing even works. Why? There's just no money/resources being spent to ensure correctness - self regulation is (and has been) all the rage for decades here in the US. Honestly, I believe in open software - and this type of software NEEDS to be opened up. I can only imagine the horrors that will be found.
