Spacing between footnotes similar to spacing in footnote

Question

I add line spacing to my main text with \setstretch{1.18} and to footnotes with \setstretch{1.22}. When there are multiple footnotes on a page I of course want the spacing between the last line of one and the first line of the next to be the same as between lines in the same footnote. By eyesight I have more or less achieved this with \setlength{\footnotesep}{.59\baselineskip}.

Is there a way to do this automatically and exactly?

MWE:

\documentclass[11pt,a5paper]{article}
\usepackage{setspace}
\setstretch{1.18}
\setlength{\footnotesep}{.59\baselineskip}
\newcommand{\note}[1]{\footnote{\setstretch{1.22}#1}}
\newcommand{\lorum}{Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Ut purus elit, vestibulum ut, placerat ac, adipiscing vitae, felis. Curabitur dictum gravida mauris.}
\usepackage{lipsum}

\begin{document}
\lorum\note{\lorum}

\lorum\note{\lorum}
\end{document}

Result:

Answer 1

Just multiply the standard \footnotesep by 1.22:

\documentclass[11pt,a5paper]{article}

\usepackage{setspace}
\setstretch{1.18}
\setlength{\footnotesep}{1.22\footnotesep}
\newcommand{\note}[1]{\footnote{\setstretch{1.22}#1}}

\newcommand{\lorum}{Lorem ipsum dolor sit amet, consectetuer
  adipiscing elit. Ut purus elit, vestibulum ut, placerat ac,
  adipiscing vitae, felis. Curabitur dictum gravida mauris.}

\begin{document}

\lorum\note{\lorum}

\lorum\note{\lorum}

\end{document}
