All this is preparatory for telling you why it is you want to choose your chain length with care. Specifically, you want it to be as long as possible. Don't try to shorten the chain in order to save weight. You specifically want to avoid forcing the rear derailleur to work beyond its limit, and that limit is generally considered to have been reached when the lower pulley is directly below the upper. Best if that lower pulley is never in front of the upper.
