Roasted in small batches for larger-than-life flavor.
Is there any evidence that roasting coffee in small batches produces more (or "better") flavor?

This probably refers to roasting in traditional drum roasters in batches.
There are basically two methods of roasting employed by commercial coffee roasters.
Drum roasting. Basically a Drum is heated from below and revolted to stir and mix the beans to heat them evenly. This takes about 15-20 minutes, depending on the desired darkness of the roast.
Hot Air roasting. Here the beans are heated by hot air and reach target temperature much quicker. This can be implemented in a continuous process for industrial scale production. Roasting times go from 3-6 minutes.
Both methods have their advantages and disadvantages. Most obvious is the different roasting time, which advocates of the drum-roasting claim to give the chemical processes in the beans more time to develop the flavor.
From a roasters perspective:
