There are several spreadsheets that have been made available for Wendler's 5/3/1. I have one that can be downloaded at
This spreadsheet not only has a log for 5/3/1 but also stats for recording max reps by weight and charts to display how your estimated 1RMs are progressing. For the log, you need to copy the previous cycle's sheet and add adjust your starting weight accordingly. I have included warm-up sets. You may want to adjust the percentages depending upon which version of 5/3/1 you are using. You will have to add your own assistance exercises to the log since there are so many options for that.
Feel free to post your estimed 1RM charts. To "easily" create images of the charts for uploading here, do a File|Save As in Excel and select web page, you will end up with 531.htm in your My Documents folder (by default) and all your images are saved in 531_files subfolder. You can delete the .htm file and the _files subfolder after uploading.
