When CF seat posts first came onto the market, lotsa folks were having problems with cracking. Probably due to improper torquing of the clamp. Anyhow, a quick and dirty way to reduce the risk of over torquing and loading one spot of the seat post was to spin the clamp around 180°. What you then had was the seat tube relief (slit for clamping) facing the back like normal, but the relief on the clamp itself facing forward. That would put most of the clamping pressure on the "whole" section of seat tube rather than the slit side. You, in effect, distributed the clamping forces more evenly around the CF seat post. This technique may be a little "old school", but does it still apply to new CF seat post?
BTW, grease the seat clamp bolt for accurate torque reading, minimize corrosion and simplify removal or adjustment later.
