Fire if Initial Value using Decrease To or Through Value

I am using a Wait for Event process flow block, and I chose the event OnContentChange for a fluid tank, and I checked the Fire If Initial Value Meets Rule box. But if the Value on the Wait for Event block is 15,000, and the initial content of my fluid tank is 16,000, the Wait for Event block fires even if the tank's content decreases slightly, even when it doesn't decrease below 15,000.

Is there a way to have this Wait for Event block to still Fire is Initial Value Meets Rule, but only fires if it has an initial content below 15,000?

I did some testing and it looks like the initial content isn't set until time 1.

See the attached model where I made a Wait for Event that starts listening at time 1 and another that starts at time 1.01

Only the second Wait for Event works as expected because of the delay in setting the initial content.
