路径上有多个标记

我想在一条路径上添加多个标记。但是，有时这些标记的位置严重错误。例如，蓝色箭头应该比红色箭头稍微靠前一点。

\begin{tikzpicture}
    \draw plot[smooth, tension=.7] coordinates { (5*0.02109, 5*-0.12607)(5*0.2274, 5*-0.1806)(5*0.4037, 5*-0.02751)(5*0.536, 5*0.4091)(5*0.768, 5*0.2045)(5*0.7262, 5*-0.02055)(5*0.8538, 5*-0.1366) }
        [postaction={decorate}, decoration={markings,
            % Red arrows
            mark=between positions 0.1 and 0.9 step 0.25 with {\arrow[red, line width=1mm]{>};},
            % Blue arrows
            mark=between positions 0.2 and 0.9 step 0.25 with {\arrow[blue, line width=1mm]{>};}
        }]
        ;
\end{tikzpicture}

Ryan Reich（谢谢！）的评论是解决方案：多个后续操作。请注意，每个“装饰块”都需要自己的装饰后续操作。

\begin{tikzpicture}
    \draw plot[smooth, tension=.7] coordinates { (5*0.02109, 5*-0.12607)(5*0.2274, 5*-0.1806)(5*0.4037, 5*-0.02751)(5*0.536, 5*0.4091)(5*0.768, 5*0.2045)(5*0.7262, 5*-0.02055)(5*0.8538, 5*-0.1366) }
        [postaction={decorate, decoration={markings,
            % Red arrows
            mark=between positions 0.1 and 0.9 step 0.25 with {\arrow[red, line width=1mm]{>};}
        }}]
        [postaction={decorate, decoration={markings,
            % Blue arrows
            mark=between positions 0.2 and 0.9 step 0.25 with {\arrow[blue, line width=1mm]{>};}
        }}]
        ;
\end{tikzpicture}
