1. You can read GUIDE Cancer DB:
2. I assume you are reading the Guide for Contact Plus 4 or Contact Plus 2
If Contact + 3 is desired, without contact, then just use the Rxx Preset for Gen1, Gen2, and Gen4.
If Gen3 is different than Gen2, then you'll need to modify the order of subsequent steps to get this included.
Or just use the table for Contact Plus 2 - and just use the 2 generators.
