I have a circumstance where we are being asked to measure when something is ZERO, but also accumulate the total before an event
It is understood that the absence of an evar would be 'Unspecified' but in this particular request the ask is to have "0" displayed along with the other accumulated digits
Judging by the absence of any documentation about not incrementing a counter evar, I assume that "=0" "=+0" OR "=-0" would not work
Further in the event of a visit that never accumulates, I doubt that a "0" would render in reporting (assuming any of the above did work)
My expectation is that the solution is to not set the evar, but only accumulate with "=+N" and assume Unspecified means the visitor has not accumulated yet
I recognize this is an outlier use case, but perhaps someone has had a similar request
