I made a spreadsheet on google docs that we can all go and input some of our roast profiles. Feel free to add as many profiles that you use, but please add comments in the comment column to help differentiate your profiles.

Lastly if you have any things that you think should be added, changed or removed from the doc just let me know.

Thanks for your time!!

Notwithstanding some of the comparability issues mentioned, I think this is a great idea, and I'd like to add some profiles. One thing that I think would be helpful is to note first 1C, end of 1C (if known) and onset of 2C (if applicable) as a way of calibrating temperature values. I've found these differ quite a bit depending upon the particulars of the roasting equipment but the onset of 1C will be repeatable for a given set up. Even though direct comparison of temperatures is probably futile, I think a lot of useful information can be had by comparing times to 1C, time after 1C, RoR during 1C, and changes of RoR throughout the profile; i.e., rate of deceleration in RoR.

However, I'm a novice to this venue and if you could offer a basic tutorial in how one goes about adding data I would really appreciate it. I tried to add data and although I signed in to Google, it didn't allow me to type anything into the cells. I presume we can just copy and paste your existing graph downward? Anyway, I'm not sure how to proceed but with the above additional data, I do think it could become a useful way of sharing data. Even the differences among various processes would be of interest.
