This is a good point, actually. I'm still not sure it works, though - at the lower bounds of visual resolution, are capitals easier to distinguish than cursive

This is a good point, actually. I'm still not sure it works, though - at the lower bounds of visual resolution, are capitals easier to distinguish than cursive letters? Because otherwise, any size capital can be compared to an equivalent box cursive, and I think the capital would be less legible. Perhaps the typically smaller eyes of cursive letters would swing the pendulum the other way, with smeary ink? I think with simply low resolution, cursive would always win out.
