The campus calculator has an exact special case: quad to science, e-bike, sunny and rush hour returns twelve hundred fifty meters, four point five minutes, eighteen meters uphill, twelve-percent battery and thirty-five calories. Outside that case it uses schematic node coordinates. Quad at one hundred, one hundred and science at four hundred eighty, ninety are about three hundred eighty point one three pixels apart; multiplying by three point one and rounding gives eleven hundred seventy-eight meters. Bars compare the fixture distance with that coordinate formula at point four pixels per meter. These are authored schematic values, not a surveyed campus route or live navigation result. Turning rush hour off removes the exact fixture condition. The general e-bike speed is twenty-two kilometers per hour, plus a half-minute wait. For eleven hundred seventy-eight meters this rounds to three point seven minutes. Bars compare fixed four point five and computed three point seven at one hundred pixels per minute. Rain multiplies speed by point eighty-two, wind by point eighty-eight and cold by point ninety-four. Rush hour applies another point seventy-eight to bikes and scooters. The route drawing passes through a central concourse, while the numerical distance uses the direct endpoint separation. The schematic is not a road network or shortest-path calculation. For the general quad-to-science route, battery uses one point one seven eight kilometers times nine point six percent per kilometer and the uphill multiplier one point twenty-five, rounding to fourteen percent. Calories use twenty-eight per kilometer and uphill multiplier one point three, rounding to forty-three. The fixed default tuple instead returns twelve percent and thirty-five. Bars compare battery labels at thirty pixels per percentage point. These are model assumptions, not measurements of a rider or battery. Identical origin and destination returns zero travel, distance, energy and calories before general minimum guards. Schedule totals add entered trip estimates and exports preserve these source rules without validating real routes.
