Will going to a higher btu water heater here waste gas?

I will increase the tank size on my two water heater system to meet the hot water needs of the tenants. I am also planning on going from 40,000 btu's to 65,000.
My concern is that if it turns out that this system's FHR is more than I need to meet the peak demand then I will be wasting gas. Will this high recovery be overkill and waste?

If the efficiency is the same, it will just heat faster when needed, so no.

The cost of the equipment upgrade will be much greater than any increase in gas cost that you should see.
I'd double-check my demand assumptions and calculations before making that investment.
