    The default delta is _one frame_ at 60fps. This is later updated - but is required early for mounted _fps_ tests.

        the total value at the target count of seconds is equal to 1.

        // 0.005

        // Add this value per frame
        total += v
        // At 3 seconds, this total == 1
