coffee filters mesh sizes and extraction

from Matt Perger's experiment:

 

 

 

in ascending order of hole size

hario paper filter: 20 nom. (30~40 meas) um

Ameuus o2 50k holes: 30 um

Ameuus o1 10k holes: 100 um

Able disk fine: 150 um?

Able disk standard: 300 um?

metal filter for handdrip: 800目, 22um

 

CONFIL有田燒陶瓷濾杯( made of alumina powder): 50 um

feebie  細粉篩粉器: 80 目, mesh 80, 180 um

 

 

VST espresso filter basket: 170um

unknown brand made in italy, double portafilter basket: 300um, 715 holes

mesh size table ( ASTM ):

  

Question:

sifting claims to reduce bitterness in cup ( i dont think it's a bad thing), and brings clarity. Most says they also let more coffee oil into cup ( wrt paper filter)

OTOH, some minor nuances might also be filtered out too, and cause less complexity/ monotonic

question: will too small hole size also blocks coffee oils?
