two things to look at on optimizing chain length. On biggest ring and biggest cog, your RD should be forward no more than 45 degrees, if it's less, the chain's too short. On your smallest and smallest, the length of chain running between the two jockey wheels should be pointing no higher than horizontal, if it is, the chain is too long. There should be enough chain wrap on most long cage derailleurs to make this do-able. Something else, you're stretching the RD cage return spring farther than it was designed to go, and it may take a set. .
