very good explaination oldboggie... using advertise duration vs 50 thou numbers makes the DCR lower so i was kinda puzzeld a bit.. But after thinking about a bit, i can see where a .050 number can be possibly a better number to go by example Cam A can be a 292/525 and cam B is 292/555, asuming both cams have the same LSA and ICL this is advertise duration and lift, even tho both cams have the same advertise duration, cam B with a higher lift will have a later ivc point and have more duration at .050 because of the higher lift, but if i were to use just the advertise duration numbers and not a .050 number than both cams would have the same icv point which i know is not correct..
