Nice article. I've definitely moved the clock to 6.

And I remember toying with the idea of 9 but I think for a different purpose, I don't remember what. Never did get that far though, I'm acutely aware that tooling is also important, but it's still oh-so-tempting.

I wonder where the company is at now. I don't think they would have moved the clock ahead but they may have moved it backwards to 12.

I don't regret my little rules engine though. It held up very well. It was intended for non-devs to be able to use, but the article is quite right, a complex set up was not easy to understand! I often got questions when things looked wrong but after much thinking the rules were usually calculating things correctly.

The alternative would have been 100 hardcodings because each client needed something different.
