it is definatley possible to gain a perfect balance, just no one can tell you.
people could edit your replay so its a perfect balance if you post it here.
also, there is even a record in the toribash book of records. [URL]http://forum.toribash.com/showthread.php?t=8349[URL]
look under the misc section, there are 2 records for perfect balance.
the one from jaker with 0 frames means he does 1 move with his tori in the first turn, which will stand perfectly in that pose for 50.000+frames.
(btw, in real life you dont move any of your body parts to stand still, u just use muscles in your legs to even the balance.)
