Where I am the eclipse was about 75% but no discernable change, at least not to the naked eye, not sure why.
On a related note, I actually enjoyed Shep Smith for the first time in my life. His eclipse coverage was downright funny at times.
See my post 279.
I’m in New York City, BTW. We had about the same coverage: 75%
Two things:
Your eyes adjust to the gradual decrease in light level by opening up the iris. (You may notice a slight change in spectral content, though, different from typical sunsets.)
Also, sight and hearing (sound level) work in a logarithmic fashion. For example, a halving of acoustical power (-3 dB) is barely discernible to most untrained ears. It takes 10x (or 1/10[x]) to sound double or 1/2 as loud, to most people. God made us this way so that we can hear very soft to very loud sounds, and yet, for example, a nearby clap of thunder, or a yelling person, does not deafen us for life.
