>that involves metrics that unclear because we don't really know enough yet
Not knowing numbers is not the same as vague or unclear metrics. For example, saying "phase 3 will proceed once the hospital occupancy goes below 30%" doesn't qualify as vague in my book (numbers and such obviously made up by me). While we don't know when that happens, the metric itself is very clear and specific.
What kind of metrics does your county's lift-up plan use that are unclear just "because we don't really know enough yet"?
You might want to re-evaluate the "lockdown skeptics" arguments in that light.
