I have put a requested R workspace on my website so that you can download it. The percentile feedback workspace compares your productivity (time spent working/time available to work) today to previous days. When I started using it, I became more productive. Here is an introduction. Here are all posts about it.
This is not for everyone. You need R installed to use it (of course) and you’ll need to know at least a little R. You must edit a function called save.ws so that the workspace is saved in the right place. I have used it under Windows XP.
