Firstly, each pole must be subtracted
by the jump height multiplied by their
index because:

let x=current pole height
let y=next pole height
let j=jump height

x+j>=y, therefore x>=y-j

Then, subtract the length of the LDS
from the total length, representing the
amount of poles needing adjustment to
conform to x>=y-j.

Though, note that the LDS must start
with 0, representing the unadjustable
starting point.
