Faster playback compresses effective runtime. At 1.5×, a 2-hour film counts as 80 minutes; at 2×, it counts as 1 hour — letting you fit more films in the same schedule.
1.5× speed: watch 33% more movies in the same time. 2× speed: double your count. 2.5× and 3× options are available in the calculator for podcasts and rewatchers.
Over a 70-year lifetime at 2 hours/day, switching from 1× to 1.5× adds roughly 3,000+ films to your total.
Roughly 33% more in the same calendar time — a 2-hour film effectively becomes 80 minutes.
Yes, in terms of calendar time. Each film's effective runtime is halved, so you fit twice as many in the same hours.
