Why my core is 129/150

This is my solution

    if len(A) == 1:
        return 0
    else :
	    x = A[0]
	    y = B[0]
	    total = 0
	    for i in range(1, len(A)):
	        dx = abs(A[i] - x)
	        dy = abs(B[i] - y)
	        mini = 0
	        if dx > dy:
	            mini = dy
	        else:
	            mini = dx
	        diff = mini + abs(dx - dy)
	        total += diff
	        x = A[i]
	        y = B[i]
	    return total
