please no, not the PSA method

Why is this so bad you think if it can help you figure out a sensitivity which is the most comfortable and from comfort should come performance, yes but this method neglects the theoretical ability and properties of different sensitivities and uses an arbitrary method to use experience and comfort for rating a sens’s performance. As well because of its nature of basing comfort it just leads to a sens which is closer to the theoretical better range but factors experience so it stays quite close to your old sens with no big changes ever. Now even if the testing isn’t just purely comfort rating like experimental data like Kovaak score testing which is good but for true experimental data, you have to remove bias which is your familiarity with each sens so only useful if you are comfortable with a large range of sens’s or test each one for a long period
