Within a bucket of width w the tilt varies by at most A·w: |a z_j − a z_b| ≤ A w

For all $\htmlData{mx=1}{a, \mathit{zj}, \mathit{zb}, A, w \in \htmlData{mx=0}{\mathbb{R}}}$, if $\htmlData{mx=1}{\left\lvert \htmlData{mx=0}{a} \right\rvert} \mathrel{\htmlData{mx=3}{\leq}} \htmlData{mx=2}{A}$, $\htmlData{mx=3}{\left\lvert \htmlData{mx=2}{\htmlData{mx=0}{\mathit{zj}} - \htmlData{mx=1}{\mathit{zb}}} \right\rvert} \mathrel{\htmlData{mx=5}{\leq}} \htmlData{mx=4}{w}$ and $0 \mathrel{\htmlData{mx=1}{\leq}} \htmlData{mx=0}{w}$, then
