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 $n_{s}=1-\\beta/N$, $\\beta=2, {5\\over 3},{8\\over 5}, {3\\over 2},{4\\over 3}$.
