I've updated the previous chart with most (all?) of Chodpaba's text predictions including today's. I have not tried to extract numbers from his graphic charts. Below is a simplified table.
On the left we have dates MM-DD followed by the actually daily high and low at Mt. Gox. In the right most columns are Chodpaba's predictions for each day below the date of the prediction. Chodpaba provided two types of predictions: explicit high low for each day (I've rounded and ignored the variance), and ~weekly ranges.
For example, under 2011-07-21 Chodpaba made four predictions for the 22, 23, 24, and 25 July. We can see the actual low for 22 July was $13.45, high 13.8, but Chodpaba predicted $13.5-14 the day before. For the 25th, Chodpaba made five predictions on that and the previous days from 2011-07-21 to 2011-07-25. The actual day's price range was $13.75-14.7; Chodpaba predicted $13.4-15 four days earlier, and skipping across $13.5-14.4 the day before. On the day of the 25th he also made a range prediction (the last column) with 13.448-14.239 inner range and 12.895-15.462 outer range over the week from 25 July to 1 August.
In order to compress the table, I've moved many of the of the later predictions under earlier predictions. So, for example Chodpaba's predictions made on 2011-07-29 share the same column as 2011-07-21. I hope that doesn't confuse too much. Maybe I'll be so motivated to put this in HTML and update it frequently. Though I only put it together as a reaction to negative posts. Franky I think Chodpaba's been solidly on, although his earlier month-in-advance were way off and he failed to predict the drop on 4 August. But on balance, I think Chodpaba'a predictions have been disturbingly accurate.
