Slope equation calculation (Is it the same as trendline?)
The forum has been broken since late 2024. I only now got a notification of your reply.
For a 4th degree polynomial, you can't just calculate the slope - you have to calculate the coefficients for x, x^2, x^3 and x^4. For OpSens CH2 to PICO CH1:
To use this to predict/interpolate values:
These values look reasonable to me.
Hey Hans,
Thank you for your input!
IDK what happened to my first reply. However, attached is one sheet of my workbook with JKPieterse's idea in the first graph.
Thanks!

Dear Hans,
I also got the notification yesterday evening.
I think what you've got there is great! and I would like to understand it a bit more. (I might need to explain this to the FDA..)
I'd like to DM you if that is possible here, and I'd be ever so grateful for a bit more explanation if possible.Again, thank you very much! Much appreciated!
