Average RoR in RT


#1

I miss having the Average RoR on my profile graphs. This was available on RTv1 and you even allowed sample interval adjustments I recall. When will this feature be added back to RT? Thanks!

That would be awesome.

I think the RoR curve would be more readable if it were smoothed a bit (maybe 5-10 second averaging?).


#3

I think average rate of rise is more or less useless, because you need information about SPECIFIC time dependent moments; charge, first crack, etc. I have found that the most important number is at the beginning. What is your maximum RoR after charge? If you can keep that high enough, without scorching, then you can control the roast from there, much more effectively. Makes sense, no?

And of course, that maximum is controlled by pre-heat temperature.


#4

If it was useless, then why does every other roasting software have it? (Artisan, Cropster, etc)

I personally find it useful, otherwise I wouldn’t have asked for it. Appreciate you sharing your opinion though.

The RoR changes dramatically every few seconds. A curve that averages out the peaks and valleys a bit would be nice.

Not talking about a single average number, talking about a smoother RoR curve.


#6

Yes. The old version overlayed the average curve over the actual curve, and had adjustable interval settings to adjust the smoothness.

It’s easy to get a single number; that’s what an average is. So everyone states it. But imagine a 10 minute roast whose average is 10 degrees/minute. One roast could have a 20 degree/minute RoR for 5 minutes, and then shut down entirely for the next 5 minutes. Another one could be 10 degrees/minute for the whole time. Same average! Different results? You bet!

What’s probably happening is that Artisans is smoothing the curve; that’s different from an average. Pardon my geeky approach here, but an average is a single number. If you take a sample of averages over time, you get a “smoothed” curve…

Yes, Artisan allows you to customize the sample rate (they recommend 3s if I recall correctly) and I believe there is some smoothing control. Which is why Artisan plots look less noisy…I keep flirting with the idea of going back to Artisan but hope the Aillio dev team can sneak in a few more updates that many of us have been suggesting. Like temp plot projection. Hint hint.

I think you are missing the point here. It takes an average every three seconds and then plots a curve with that data. Just a smoother RoR curve…
