Let $A(x)=\{n(n+2):1\le n\le x\}$. For squarefree $d\mid P(z)$, suppose
\begin{align*}
|A_d|=\frac{\omega(d)}{d}x+O(\omega(d)),
\end{align*}
where $\omega$ is multiplicative, $\omega(2)=1$, and $\omega(p)=2$ for odd primes. There is an absolute constant $c>0$ such that, for $z=x^{1/u}$ with $2\le u\le c\log\log x$, an even Brun truncation depth can be chosen so that
\begin{align*}
S(A(x),P,z)\ll x\prod_{p<z}\left(1-\frac{\omega(p)}{p}\right).
\end{align*}
The implicit constant is absolute.
