For me, missing a night of sleep has a much, much larger cognitive effect than missing a cup of coffee. What I was trying to express was that the percent change is much higher, not that it’s infinite. Trying to be more practical and a touch less sarcastic for a minute… I find, on average, I tend to get about two hours more work done on days where I spend at least 45 min in the gym and that includes the hour or more loss from the activity itself. Skipping caffeine on the other hand, doesn’t have any effect unless I’ve missed sleep the night before. If you are thinking of dipping your toes into supplements though and don’t really want to exercise or sleep, I’ve found Creatine to be really helpful in that state. Definitely a stronger effect than caffeine but takes a lot longer to kick in!
