Even after car is warm the coolant fluid is still low.
@Jfheisenberg ........ I'm ah feared you are overthinking your situation.

Points to ponder:

Assuming no leaks in the cooling system, most of the loss of the coolant mixture is due to evaporation/dissipation of the water part of the mixture. A simple check of the vapor pressure of ethylene glycol compared to the VP of water will show that.

The blue coolant stuff is roughly 50% water.

Therefore, most of the mixture that is disappearing (not leaking) , is water.

The system holds about 7.5 ish quarts.

I might take a pint of liquid to top it off.

So, if the system is a little low, why not top it off with distilled water.

The manual says to fill the reservoir up to the full mark when the engine is cold.



Now, relax ........
