I left a detailed response; I don't know if Paul is referring specifically to the Madgwick filter. If so, I think he is mistaken...

Hello Cris
Thanks for all the info you share! There are several threads discussing the topic of multiple iteration of Madgwick filter but still need clarification on one point.
You are saying that a rule of thumb is to use Madgwick iteration frequency as about 5 times of IMU sampling rate. So if IMU sampling rate is 200Hz need to run Madgwick at 1kHz. But what should be sampling frequency parameter at Madgwick at this case?
For example, I use Data ready interrupt at 6050 and get data from 6050 every 5ms (Sample_Freq = 200Hz). After I read all data from 6050 I am ready to run Madgwick. But if I want to do lets say N iterations do I need to use the same "fresh" portion of data and (Sample_Freq * N) at "Integrate rate of change of quaternion to yield quaternion" or?
Thanks in advance!

Thanks a lot! Now is clear. Intuitively such iterations using the same input data feels weird but math is a fun thing, would be interesting to model that and see if the result is really approaching asymptoticaly some specific value.
