  We show that a combination of the simplest $\alpha$-attractors and KKLTI
models related to Dp-brane inflation covers most of the area in the ($n_{s}$,
$r$) space favored by Planck 2018. For $\alpha$-attractor models, there are
discrete targets $3\alpha=1,2,...,7$, predicting 7 different values of $r =
12\alpha/N^{2}$ in the range $10^{-2} \gtrsim r \gtrsim 10^{-3}$. In the small
$r$ limit, $\alpha$-attractors and Dp-brane inflation models describe vertical
$\beta$-stripes in the ($n_{s}$, $r$) space, with $n_{s}=1-\beta/N$, $\beta=2,
{5\over 3},{8\over 5}, {3\over 2},{4\over 3}$. A phenomenological description
of these models and their generalizations can be achieved in the context of
pole inflation. Most of the $1\sigma$ area in the ($n_{s}$, $r$) space favored
by Planck 2018 can be covered models with $\beta = 2$ and $\beta = 5/3$. Future
precision data on $n_s$ may help to discriminate between these models even if
the precision of the measurement of $r$ is insufficient for the discovery of
gravitational waves produced during inflation.
