以定義的距離垂直重複框

Question

使用以下程式碼

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty
\usepackage{verbatim}
\usepackage{tikz}
\begin{document}
\begin{frame}[t]
\frametitle{}
\newsavebox{\recA}
\savebox{\recA}{
\begin{tikzpicture}[scale=.6]
\pgfmathsetmacro{\incrmnt}{1.618*.88}
\draw [thick, black, fill=red] (0,0) rectangle +(1,\incrmnt);
\end{tikzpicture}}
\newsavebox{\recB}
\savebox{\recB}{
\begin{tikzpicture}[scale=.6]
\pgfmathsetmacro{\inc}{1.618*.88*2}
\draw [thick, black, fill=red] (0,0) rectangle +(1,\inc);
\end{tikzpicture}}
\begin{tikzpicture}[scale=1]
\foreach \X in {1,3,5,7}
{\node[blue] (y-\X) at (0,\X){\usebox{\recB}};}
\end{tikzpicture}
\begin{tikzpicture}[scale=1]
\foreach \X in {1,...,4}
{\node[blue] (y-\X) at (0,\X){\usebox{\recA}};}
\end{tikzpicture}
\end{frame}
\end{document}

產生了下圖。這取決於縮放和 foreach 序列；這不能讓我精確控制盒子之間的垂直和水平間距。

我想以精確的垂直間距重複矩形，如下圖所示。
