Like a swimming pool.
Water takes a while to heat up but once it does it takes a lot to cool it off.

Big reason for our climate here in SE La.
Once the gulf warms up we seldom see temps above 100 but seldom see temps below 70.
The water keeps us cooler in the day and warm at night.

So it is not the amount of water or the size of the cistern.
It is the surface area of the water against the cooler earth.
The center of the water mass is not giving off heat because it is only next to warm water and not the cooler earth.
He would do better having 2 inches of water over the entire basement than a pool of water in a cistern.

Then there is the humidity factor of having water in the basement to consider.
Humid air always feels cooler or warmer than it really is.

So some of us understand your calculations and can follow your reasoning.
And others no amount of math will convince them or prove them wrong.
