Unless you get above 95% it is not really exciting, I remember being a bit disappointed in 1999 when we had about 97%.
The problem is that below 75% the change is hardly noticeable and even at 90-95%, it is probably ligther than before a storm.
It is only at 99-100% when you actually see the corona effect and it gets really dark. And given how short lasting it is the temperature drop is not likely to be significant, especially if you are not in the path of totality.
It is still interesting though, but one probably feels more excited about what is really going on than what they see (when it is not total).
