I'm waiting up tonight for the answer
I've not had the chance to tinker with this yet. Hopefully I can help test and give some insight on it.

ahhhhh I need to know the answer to this!!
do we get an option for how many frames/seconds our 'window of change' is?
per a talk we had in the moderator section...
should be dx/dt
use could be something as simple as [send.90.dx/dt]
it reports the difference in TPS +/- from the last frame..
currently no option to change the amount of frames it uses...
-Scott -
abs([PID.17.dy/dx])
or
[PID.17.dy/dx]
Returns actual TPS with two decimals. This is not what is expected.
edit
you mean literally that dx/dt need to be used...
No, using dx/dt returns the same (actual value) as dy/dx with or without (obviously but just mentioning) ABS.

ideal is not the word you're looking for, more like 'inflexible.' some things change quickly, others change slowly, so you have to regulate the duration of the change, cant just rely on fixed and arbitrary intervals.
I'll rephrase... for what I want to do, the change since the last frame would be ideal.

so with the syntax available, how would I express 'change of change?' Laplacian of Gaussian is a common noise reduction technique, which would be hugely useful to us.
i discussed this further internally and i think the best way to go with it in future will be to simply have a reference to the previous frame value of any PID and also the time between frames eg. [PID.17.old] and [PID.17.time] or something similar.
This way you can implement derivative functions, simple lag filters using any coefficient you want and any other formula you can think of without needing us to code it in.
eg.
FastFilteredValue = PID.17.old + (0.9 * [PID.17 - PID.17.old])
SlowFilteredValue = PID.17.old + (0.1 * [PID.17 - PID.17.old])
DerivativeValue = (PID.17 - PID.17.old) / PID.17.time
I count sheep in hex...
Is there any other information on this feature?
I like the idea to code it as a variable that you can change...
perhaps a setting for dt somewhere in the main options section of the scanner
dt= ___ Frames
then it could be used as pid.17.dx/dt and it would automatically return a value based on the difference from the dt value set in the options
as an example dt=5 would return the change in value over 5 frames
we could also use a way to average things..so you could get the average change in real time vs plotting the average in the scanner...
sometimes it would be better to get a constantly updated average over a given period of time vs the total average for the entire log.
Maybe an Average over time setting? AOT=600 would return the average over 600 frames...continuously updating...dropping early values ad keeping the latest values
