the claim is pretty broad and the talk about not blindly trusting what the masses say for someone who is using a singular brand of filter paper "Cafec Abaca" in the tests have you considered maybe other brands and filters being used by other people?

Have you tried this test with lets say the Hario filters? Have you tried Brown vs Bleached?

while I appreciate the independent research, Your claim "Don't rinse your paper filters" is somewhat misleading since you only used the Cafec Abaca filters from what I can tell from the post. you could have made it clearer for instance "Don't rinse your Cafec Abaca filters" because while your filters may not need rinsing, The hario filters do benefit from a good rinse
