This is a knife that I sharpened, and since I don't have a PT50 Tester, could anyone give me a rough estimation of what my BESS score is:

Here I could make the hair pop, but I used a bit of side to side, and it wasn't reliably popping 100% of the time


I saw a video someone tested a new razor blade using this technique, I don't know if this is considered a "cutting free hanging hair"




I didn't video the part where I split a hair in half, I tried splitting that same strand, that same section but it broke off, so this would be consider a "hair splitting", not "hair whittling" right?

I found a write-up regarding comparing BESS score with real world test, in it, the author said that an edge that could "cut a free hanging hair" is at least a 70, and "hair popping" is at least 30.

What do you think or estimate my score is? A precise number is obviously impossible to give, a range is plenty okay. Maybe 80-70, 70-60, 60-50? Thanks
 
I don't think the BESS score is precise, because way to many variables are at play, including the quality of the hair.

In Knife Deburring, Dr. Vadim Kraichuk says, the "violin" sign is when you can't cut the hair, but the cuticles catch the edge. This is 115 BESS.

You can cut a free hanging hair at 70 BESS.

You can split a hair at 60 BESS.

You can pop a hair at 30 BESS.

At 20 BESS, the hair just falls effortlessly as soon as touched by the edge.

At 10 BESS the hair explodes and could cause catastrophic damage to anyone within a city block.

I saw Shawn Houston's video where he sharpened single bevel knife to 4 BESS, he got to be careful cause he's gonna cut through atom and make a nuclear explosion some day.
