Sure, I'm not saying what the ideal trade-off is. I'm just saying: - The current accident rate due to lack of redundancy isn't too awful. - Adding redundancy increases cost, even when it seems like you have the same total power or whatever. My bias is towards a bit more redundancy than we have now, but not massive changes.
