On my last service change, th PoCo hooked up yesterday, and lo and behold, put a dinky 10KVA Xformer on the pole.

The customer's original complaint was dimming lights, due mostly to the 300' long secondary, and a 60A service, circa, 1950, which I assured would be cured. (Bad mistake)

But... She plans to buy an electric on-demand water heater, which uses two 40A 240V circuits to feed heating elements.

So, I figure, if dimming lights still isn't a problem (I saw some flickering myself...) it will be...

Am I correct in asking for, say, at least a 25KVA?

The house demands out at 26KVA.
