I think the elastic role of tendons needs to be taken into account here. A longer tendon stores more elastic energy, and this length is related to the length of the muscle itself. Take the ‘high calf’ of most top sprinters. A long calf muscle would have longer muscle fibres, but a shorter achilles tendon; far from ideal.
