Cam specs are usually opens x degree BTDC closes at x degree
Since intake opening is stated at 0 and exhaust closing at 6 doing it your way maybe thats why you end up between thoose 2 values...
And it should be measured with the correct gap at lifter...or you get "happy" values of duration and lift.
