Might have gotten better at calibration. I've been bookmarking about 55 items of various prices on a wishlist, and wanted to figure out their total price. I could have made an Excel document with all the prices, but I lazed out of it and assumed their average price was 400 (of my local currency), and computed a total from that. Eventually I did make the spreadsheet. Lo and behold, the calculated average really was 400.48! It's probably my most accurate estimation to date. (Sure enough, n=1, but other instances of calibration haven't been so accurate as to be this memorable.)

Now, to actually get to earn the money for that total price...
