It may be missing a prefix. Usually it is "ATDC or BTDC" in degrees etc. I would check with the cam company, or do some checks at 50 thou and see what you come up with. It may match what you have. This is what the card should have. I allways use the 50thou figure for degreeing cam.
Cam Timing: TAPPET @.050
Lift: Opens Closes Max Lift Duration
Intake 18 BTDC 48 ABDC 103 246 °
Exhaust 59 BBDC 17 ATDC 113 256 °
Can you scan the card and post it, or atleast give us all the details off it exactly?
