You could share measurements and graphs, and those can be reliable, but everyone gets different measurements. Also, you have to trust that the person correctly modded and measured the product. Even the people who are best at measuring make mistakes on measurements, both crinacle and oratory had issues in the past. I would still trust their measurements, but in this one case, oratory was the only measurement I saw and he admitted he didn't fully remove an adhesive material that was impacting the tuning. When I asked him about this, he admitted that if he was able to fully remove it, it would have changed the sound to some degree but he didn't get that far. I could see how this amount of effort turns off many people, but some people are willing to put in work for something if they're saving money.
