I ended up with an hour in the club. I will admit that I changed from my usual upper deck seat, to one near the door--so I could be one of the first off the plane.
With Global Entry, PreCheck, and an early arriving flight, 1h34 is more than enough as you've proven.
Without Global Entry (especially if you're using the non-citizen lines), no PreCheck, and a late arriving flight there's a real chance you wouldn't have made it (depending on other arrivals around the same time).
There's no single answer to questions like this - it's always down to your exact details, and just a little bit of luck...
