I always read spoilers and still watch bc:
I love watching the spoilers go down (if they end up playing out correctly).
It’s still entertaining to me, and I usually don’t have to deal w/ all the anxiety surrounding who the F1 is, or at least have an idea of who not to get too attached to, I guess. Lol
And to answer your first question, in my experience of watching for the last 15+ years and iirc Reality Steve has been on the money a decent amount of times, but in the more recent years he has missed the mark more than he has in the past (imo). Some seasons the spoilers are vague and minimalistic bc word of that season’s potential spoilers was a very well kept secret.
He seems to get it down to the final 4 at the very least, and a good chunk of the time down to the F1 and F2 but may not know which of the final 2 is the F1. I feel that when he has a F1 spoiler to reveal, he has been right a good amount of the time. I will never forget the biggest let down for me. His spoilers for Brad Womack’s second season as the Bachelor was a major let down. That’s when I really learned to always keep in mind that at the end of the day Reality Steve is only human, and to keep a little skepticism around any spoilers revealed.
