What incline do you guys walk at?

[Aggression]

When you guys walk on the treadmill, what incline do you guys walk at?

Also could you guys tell me your walking program:

Days of week
Pace
Incline (if any)
Minutes

Also what is the benefit of walking on an incline?

[Hypertrophy]

Whatever it takes for your body to reach a steady state in your desired target heart rate range.
40-60 minutes (depends)
3-6 days/week (depends)

Having more of a incline will also stress the calves more. The pumps & higher bp when on d-bol may cause some extra pain when at higher elevation. But the heart rate goes up too which is what your trying to do anyways.
