Well it's hard to visually inspect this long text; let's look at it.

$\begin{matrix} \textrm{Secs} & \textrm{GroupR} & \textrm{GroupS} \\ 45 & 1 & 0 \\ 50 & 2 & 1 \\ 55 & 1 & 1 \\ 60 & 2 & 2 \\ 65 & 1 & 0\\ 70 & 1 & 2 \\ 75 & 1 & 0 \\ 80 & 1 & 1 \\ 85 & 1 & 0 \\ 90 & 2 & 2 \\ 95 & 1 & 1 \\ 100 & 2 & 1 \\ 105 & 1 & 1 \\ 110 & 2 & 2 \\ 115 & 1 & 1 \\ 120 & 2 & 1 \\ \end{matrix}$

Based on visual inspection the averages look about the same.
