It would be neat if someone had a page (like that handy calculator at http://www.alloscomp.com/bitcoin/calculator.php) that projects what the next difficulty adjustment will be.

projected difficulty adjustment multiplier =

&nbsp;blocks\_since\_last\_adjustment / 2016<br>
&nbsp;\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-<br>
&nbsp;time\_since\_last\_adjustment / 14\_days

For instance, if it already got half way to the next adjustment in only 3.5 days instead of 7, we would expect difficulty to double:

&nbsp;(1008/2016) / (3.5/14) = 0.5/0.25 = 2.0

Also, it could show the predicted time when the next adjustment will occur, and tell when the last adjustment was and how much it changed.
