If you want to play around with this a bit, pull from my tableheadings
branch on http://repo.or.cz/w/org-mode/org-tableheadings.git (it lists
the git or http URLS to pull from on the page)

I've implemented "calculation separators" that register as hlines for
table formulas, but are ignored when row groups are constructed for
export.  Your example table would then look like this:

--8<---------------cut here---------------start------------->8---
  |   | Strategy | Average performance |
  |---+----------+---------------------|
  | / |          |                8.69 |
  | / |          |                9.72 |
  | / |          |                9.03 |
  |:::+::::::::::+:::::::::::::::::::::|
  |   |        1 |                9.15 |
  |:::+::::::::::+:::::::::::::::::::::|
  | / |          |                9.15 |
  | / |          |                7.60 |
  | / |          |                7.46 |
  |:::+::::::::::+:::::::::::::::::::::|
  |   |        2 |                8.07 |
  |---+----------+---------------------|
  #+TBLFM: @5$3=vmean(@address@hidden);%.2f::@9$3=vmean(@address@hidden);%.2f
--8<---------------cut here---------------end--------------->8---

This should then export the way you wanted without any fiddling.  Let me
know if you find any bugs (the test suite is clean, but test coverage
with tables is sketchy).

Achim.
