I think there's a bug in this. If I answer "Will data records ever need to be updated or deleted once they are written?" with "No" it says "You Don't Need a Blockchain Blockchains do not allow for modification of historical data. Consider a database." It seems like blockchains actually meet that requirement per my entry?

Yep I hit the same bug, if you answer “yes” the next question has the same bug.

The problem are the double negative questions. They should be reworded into positives to remove ambiguity.

Just fixed the wording to match the actual NIST flowchart. Thanks.

I realize this isn't a life's work, but can you support the back button? Some of the questions are double-negative-ish, or maybe I'm just not a morning person, either way the back button to revise answers without having to go through the whole thing again would be useful.
