Irrespective of how much you can bend, twist, turn, jump, the things that really matter is that you are learning and enjoying the process. There have been innumerable times when I have tried a pose, sometimes for 45 mins, and given up only to find that my body just eases into the pose the very first time during my next session. Your body-mind-soul system is an extremely intelligent system and has its own way of learning and integrating your practice. Even while you are not in pose, your mind and body will process your efforts and continuously learn, even while you are at other activities. Trusting your body that it will learn is an important truth in the process of mastering advanced poses.
