Lift. We can also look at the lift achieved by targeting increasing percentages of the customer base, ordered by decreasing probability. The lift is simply the ratio of the percentage of responders reached to the percentage of customers contacted. So, a lift of 1 is equivalent to no gain compared with contacting customers at random.

• ### Lift Formula - NASA

Jun 12, 2014· To understand for lift formula that determines aircraft lift capabilities. Concept: An aircraft's lift capabilities can be measured from the following formula: L = (1/2) d v 2 s CL. L = Lift, which must equal the airplane's weight in pounds; d = density of the air. This will change due to altitude.
