A suggestion - when you submit the anonymized data, submit it as a new post under the Optimization Lab category.
Optimization Lab is a relatively new initative we started this Spring to do a deep dive focus on submitted measures that are running slowly. It is led by our resident DAX superstar @AntrikshSharma , and for the selected measures he does a deep dive video where he walks through and explains why the measure is running slowly and what can/should be done to optimize it. I think your measure would be an excellent candidate for the Lab.
