I call that consistent behaviour
But seriously: Having done a few BTC tx lately (and waiting from hours to days to get it confirmed while paying 0.5 - 2$ fees and at the same time most LTC blocks were empty or had 1-2 tx) I really see good use for LTC as the crypto currency for fast payments while BTC probably shifts toward long term holding/storing over time.
Nowadays it is almost impossible to pay amounts of 1-100$ with BTC when you pay almost the same fees as with Paypal and still wait an eternity or longer to have your tx mined. LTC on the other hand is great for transferring amounts in this range very quickly and at extremly low fees.
I believe LTC will be used for payments at more and more e-commerce sites in the future because of its speed, reliability and competitive fees. Also once the pump on BTC is over ( I actually see its non-hyped value somewhere between $800-950 atm) LTC will probably get its well deserved attention. In this context I do really hope that Segwit will come true.
I agree that the connection BTC goes up, LTC goes up is over. LTC has grown up and doesn't follow his big brother anymore
