No the exact opposite is what they mean... to focus at infinity, you aim at a distant object. You will find the 4x5 view camera bellows is closed up most of the way when you are at the right focus position for a speed test.
Then without changing the focus position, fill the ground glass with the blurry test target.
If you did it the other way, and you stretched out the bellows... that could explain why your test seems to indicate 32 speed.
--- There isn't one cheat sheet reference for film speed testing because everyone does it differently and everyone has their own write-up they like ---
I have my own ideas too, but I don't want to make things complicated for you right now.
If the bellows extension was your problem, you might test again focused at infinity.
Otherwise, you could do no harm shooting a 200 speed film at 32. I once had a test problem and found 64 speed for a 400 speed film. I went around for a year shooting that film at 64 and got some of the best pictures of my life.
