Tactics Ratings

Has there been a change to the number of point rewarded for correct answers? I am getting very few points for solving puzzles that are roughly equal to or below my rating but still taking large rating deductions for incorrect answers. I have lost over 100 rating points in about a week so I suspect there has been a change in the point calculation. 

It is pretty aggravating because it means there is really nothing to gain from attempting puzzles that are roughly equal to my rating. I will need to answer 3-4 correctly to equal one miss. I don't get to select the puzzle difficulty, so if Chess.com keeps throwing low rated puzzles at me (which it does), I am bound to miss a few here and there and drop rating points.
