(On average), for a walk to the stop of 100-200 feet the bus would need to stop every 200-400 feet. 300 ft seems to be roughly 100m, which is probably much too short a distance still. 250m or ~800 ft aligns better to my experience with cities with good transit, and in the worst case scenario you have to walk 125m to your nearest stop.

Almost.

1/8th of a mile is every 660 feet, but the farthest you can be from one is the midpoint so 330 feet. However for every trip starting at the midpoint there’s another at and the bus stop thus the average would be 1/2 that distance again or 165 feet.

Assuming a 1D world, you can beat this in practice.
