Hello Yanninck, I can understand your objective , not to produce setfiles. However can you able to suggest us where to start, I read your optimization articles and i know the basics and how to optimize. That would be very helpful, if you or your team provide a some default setfiles along with which parameters and suggested steps needs to be optimized.(Screen shot enclosed with tick mark). So that we can ignore the non imporat parameters. at this point Optimization is taking numorous hours.
