Looks to me like it is requiring the duration @ .050 and under those the duration @.006.
Intake dur@ .006 275
Exhaust dur@ .006 270
look to the right of the input columns and you can see the
.050 then under it the. 006.
If you look at your cam spec card it has it listed like this
duration. 006 tappet lift intake 275
Tappet lift exhaust 270
hope this helps
