Batch size does impact utilization to an extent- but not in any meaningful way at the homebrew level.
When you make a 25 gallon batch, just scaling everything up times 5 is close enough. It's not much of a difference. Taking it from 5 gallons to 50,000 gallons would make a difference. But at a smaller size, it's pretty negligible.
