Trying to show off has consequences

Why is it when I shuck recording for the tutorial I'm trying to put together and play a new game by itself, I always do better than when I'm trying to record the game and narrate my decisionmaking?  I think the game knows when I'm recording, lol.  Whenever I try to record, my spells seem to miss more often, especially my first Tame ... but for now I'm playing a bit for fun and right off the bat I tamed not just a spider, but a Ravenous Harridan.
