Absolutely, as a slight counter to my ADHD and laziness. I find it harder to say "let me sleep fifteen more minutes" when the timer or alarm isn't a round number.
I set most of my timers using Siri and avoid 30, 40, 50, and 60 exactly because I can’t seem to emphasize “TY”in a way to distinguish it from “TEEN”. My wife needs to me to clarify those too, so it’s definitely a me problem, not a Siri problem. I instead go over or under a minute or two, depending on the task.
Yeah, i just pull the dial and let it settle where it settles. On my alarm clock my alarm will not go off if I set it to specific times like 7:30 so I usually do weird times in an attempt to get around that.
