It does sound like the cam timing is retarded slightly since the piston is reaching TDC before the cam reaches the intended orientation. The angle at the crank is twice that at the cam and it looks like it's off by about the same angle as between LT and LF, which I think is 5° at the crank.
Thinking about the cam sprocket, I believe there are 33 teeth, so one tooth is equivalent to about 10.9° at the cam, 21.8° at the crank. Thinking in these terms it's off by about a ¼-tooth on the cam sprocket. Doesn't seem like a huge amount in those terms.
Here is a thread about cam profiles that might be helpful. I'm curious what others have to say about this.
