So in a nutshell you're saying if I CAN miss items that make me complete the game faster it is any%?

So I'm new to Speedrunning and I saw a guy do an any% run and got 32 minutes, which he claims is the world record, however I bet that today, but on one of the levels I used a strategy which might define my run as a low% but I'm not so sure. On one of the levels I was supposed to collect 8 pages, but instead I collected 4 and let slender "grab'' me, which triggered the next level, because I didn't get all 8 pages does that mean mine is a low% run?

I did my run on an Xbox One, for anyone who asks.

When the video has uploaded (My internet isn't great) I will post my video and you can see for yourself.

Thanks for the help and I hope someone can help me solve this.
