When saying the Hallel on Sukkot one waves the 4 species at certain points. According to the Artscroll Machzor that I use, there are wavings that differ for the chazzan from what the kahal does (page 294). In the "hodu" section (Tehillim 118) the chazan waves when he says the first hodu line, and the yomar na yisrael line and that's it, while the congregation waves at each hodu.
When an individual davens without a minyan, does he assume the role of the chazzan and wave twice, or of the congregation and wave 4 times?
