Alright, so for what the rolls mean: Basically the DC to avoid issues was 97, but development rolls were in fact high enough in total to resolve the various issues. During the design/build process, the majority of the focus was put into the ECM and operations which had most of the work thrown into them. However, thanks to your high development roll, you're able to get a system upgraded in quality compared to the initial design. Additionally, the nat 100 gives another fun toy to play with.
