What reflections do you have putting this into action over the year since that post?

BTW, your blog is one of my absolute favorites!

It's been about as useful as one would expect. I don't need it daily, but when I need it, I can usually estimate a good enough answer in the time it takes someone else to do it on a calculator.

It has also helped a little with getting a geometric appreciation for numbers, but I suspect that could be improved significantly with more active practice.
