So, there’s data supporting DST costing lives, saving lives, and not having any impact either way. I cherry-picked a few to illustrate the former, which paired with yours make for a more complete picture.

Overall, estimates on the lives lost side appear to be numerically higher; so taking ALL of it at face value, getting rid of DST would save more lives.

I’d vote to chop it if saving lives is your chief concern.
