Absolute minimum $0.01 per point...anything over 1.5 cents per point seems pretty good to me, but the professionals will want more. 2 cents per point and I am happy.
So 25K points for a $400 ticket is about my goal.
I have done worse - 60K for a $700 ticket - and I have done better - 150K for a $5000 BE ticket, although I valued it at $2500 for myself (what I would have been willing to pay for BE), which is the correct way to calculate it, I believe.
