I am doing RI for a year now, I can do all the exercises, but in my normal playing I still cannot play rolled in. Does it have any sense this way?

Unless you have a fat, stable high G I would suggest to stick to the exercises.The goal is not to learn how to play rolled in, the goal is to make the lips move in more or less the right direction and thus to play more efficiently. It is very well possible that small elements of RI are already part of your 'normal' embouchure.That you do not look like the kids on the cover of BE is not important. BE is not an embouchure but a set of exercises. If, on the other hand, your playing is exectly the same as a year ago, then I would advise you to check if you are doing the exercises correcctly. A year should give some results IMO, however small.
