vivitar pn2011, is it possible to use 100 speed films?

[TheGreatGasMaskMan]

So two years ago, I picked up a vivitar pn2011 with fujicolor 200 in it, but this year decided I wanted to run a fuji pro 400 through it. it worked. I just finished (but haven't developed) a tmax 400 from the same camera, and just loaded a retrochrome 400 into it. While I'm sure 200 will also work fine in daylight, I was wondering if 100 speed will work given I have enough light.

Also, I'm only just shooting this camera for fun.
