Calculating OPR

Hello everybody!

I would like to know how OPRs are calculated. I assume there is a thread about it somewhere, but I couldn’t find one. I would very moch appreciate it if someone could explain the process or provide a link to a post that explains it.

Thanks in advance!

Ed Law’s presentation does a good job.

Thanks :smiley:

You will find a detailed explanation how to calculate OPR in the link below. What is your math background? Truly understanding what OPR is doing requires some knowledge of linear algebra. If you want to play around with it and try writing your own computer program as a learning exercise, I can help you through that process.
