RDT- Does it make coffee better? (Exploring the Hendon study with Timemore Sculptor 078S)​⁠​⁠​⁠ ​⁠

This video discusses the recent study by Professor Hendon titled “Moisture-controlled triboelectrification during coffee grinding”. I have discussed the most interesting part of the study which is about the effects of RDT on coffee charge and extraction. I have also discussed the surprising results of my experiments with RDT using the 078S grinder.
Edit: At 25:51, the visual should read "Less water and leaving the beans soaked till the water is absorbed, both increase the speed of extraction".
The study can be found at doi.org/10.1016/j.matt.2023.1...
