Seat misalignment caused by body/leg misalignment?

[Bobinator]

On two separate recumbents, A RANS Tailwind and now a Lightning Phantom II, I have noticed that over
time the seat is misaligned to the left. On the Tailwind, I actually bent the seat frame, which I
had to replace. On my Phantom, the seat was off center, listing slightly to the left. You can see a
noticable difference on my leg as well. The Soleus muscle is more defined (bigger) on the left leg.

Anyone experience something similar? Cleat placement is pretty close. I suppose one leg is longer
than the other. Other than the necessity to realign the seat, I have no leg problems.

If your leg difference is significant i.e. 0.5mm or more, it might be worth considering using
different length cranks on each side of the bike.
