Since 8 hour jet lag requires only a night worst case two of sleep to adapt, why is this 1 hour such a big deal.

Going west, you'll be sleepy very early in the evening, but then no one is really stoping you from going to bed at 7 PM and staying in it for twelve hours straight until 7AM (you probably will wake up around 2-3 AM, but there's nothing else to do at that time, so you'll probably stay in bed just out of boredom). As the result you adapt pretty quickly.
Going east is much harder: you can't fall asleep at night, and then during the day you have things to do, so you end up sleep deprived for quite long.
Secondly the supposed benefits have never been backed by aby hard-evidence, it's all make-believe.
Science says it's more like 1 day for every hour of shift. I agree that when I shift 12.5 hours to go to India the worst effects are over after a few days, but I don't get back to a normal pattern until two weeks later as I return home.
