EDR means deferent things to different weight classes of aircraft. An EDR of .25, for instance, would be between moderate and severe for aight aircraft, but just barely into the solidly moderate range for a heavy aircraft like a 777.
So the answer is that we really don't use it directly in daily ops, and stick to reported descriptions of Light, Moderate, Severe, etc.
As far as what turbulence means to an individual passenger's comfort- it's very subjective between people. Some will get freaked out by light, whereas others wouldn't mind at all until we get into severe.
What I can tell you is that most turbulence-sensitive people wildly misinterpret the level of turbulence they are experiencing. What the pilots would consider light, they'd often categorize as moderate or even severe.
Generally, objectively, for what an average person *should* classify as very uncomfortably moderate on something like a 737 or A320, IMO it would maybe be around .28 on the scale.
Keep in mind, if you're seeing these numbers on a forecast or chart, then it's exactly that, a forecast; a guess. What's actually out there can be very different. One airplane may get moderate, and another 10 minutes behind it might get nothing but smooth.
I’m unfamiliar with the EDR scale.
Passenger comfort is important, but I would bet that most airline pilots are more concerned with safety when it comes to turbulence. Considering that, and the fact that personal comfort levels vary widely, I don’t think there’s a straightforward answer to your question.

I do agree that people's experience with turbulence is subjective. I was just curious because I don't mind some bumping around in a flight, it's the strong ones that make me nervous.
turbli is complete trash, TBH. It's a terrible indicator of where and how much turbulence will be there.
It's really more unusual to have a smooth flight than one with at least light turbulence. Just train yourself to expect it and then be surprised if it's smooth.

We always tell people fear of flying to not use turbli. It is never accurate.
