I suspect when fatties make outrageous claims like this, it's due to their stupidity. For example, my treadmill marks speeds from 0mph to 6mph, but it doesn't say "mph", it just states the numeric value. 3.5 (~17 minute mile) is a decent walking speed. If the fatty is "jogging" at 4.0 pace (4.0mph, roughly 15 minute mile) they probably interpret the 4.0 as a 4 minute mile. That is my only theory on how an obeast could be stupid enough to think they run faster than Olympic atheletes. Edit: fixed autocorrect errors
