Instead of 1% changes of the onscreen gradient indicator, I feel it would be better if it were at the very least 0.5% changes.

Riding on the coastal loop, it seems like there are a lot more minor grade changes than is apparent watching the number shown onscreen. Riding a 0% grade feels like it is actually fluctuating between +0.8% to -0.8%. Giving a better indication of the gradient would help my brain interpret the "false flats" that are hidden in the 0% gradients.
