Artisan feedback

I guess you can search for "flick" or being more dramatic , "flick of death". Anyhow, it's a term coined by Scott Rao, who also have written "The Coffee Roaster's Companion". (You'll find all the background knowledge in discussions on RoR (DeltaBT in Artisan software). These discussions most often have some kind of reference to "Rao's commandments".)
The "flick" denotes when this RoR flicks upwards in the middle of first crack. This often happens when you don't do anything while entering 1C. As the bean mass goes through a change in 1C, you have to anticipate what is going to happen. Personally I usually take down the heat to a bare minimum and just about max out my fan at about 30 sec into 1C. That is actually done while my DeltaBT/RoR is already diving (which is a normal reading after some 20-30 sec, due to the steam leaving the beans). I usually don't try to counteract on that "dive", as I would get a terrible flick afterwards if I did.

Here's Scott Rao himself on the subject of The Flick

Interesting!  In the graph in the article he said was "typical", is the rise before FC considered a flick as well as the one at end of FC?

It is not the  flick, it is just a rise in the ROR.
It is also not a good thing. According to Rao, the ROR should decline steadily and smoothly throughout the roast.

Thanks...i went back and re-read what he said.  The flick is the tail end...

I'd say you can get a flick anywhere in your RoR curve, and wherever/whenever that happens, according to Rao it is not a good sign.

Of course the flick after the end of FC is the most typical one - and that is the one often called "The Flick of Death" as mentioned by Hank above.

Said that, when analyzing my RoR, I usually don't care about small (i.e. less than 10-15 secs) flicks, as I believe these are usually normal temperature fluctuations.

Exactly.

The flick does occur during 1C but it is not an island unto itself; it occurs as a result of the correction for 'the dip'.

I love how everyone has a wealth of knowledge.  This is great!  I'm sure everyone answers the same questions over and over, but just so you all know I really appreciate all the help.  I'll post another graph in the next few days and see what everyone has to say. Thanks
