A parallel entry places the airplane on the non-holding side of the fix, so...
Well, that's the way we all learned it, isn't it? But the way "our boxes" do the teardrops -when they should be doing parallels- is by turning before the station/fix instead of overflying it and going into the non holding side. This non standard "fly by" philosophy could also be implemented to the parallel entry thus not putting the aircraft in the non-holding side.
The only explanation to the teardrop over parallel choice I can come up with is the following:
At the end of the teardrop you have more room before passing the station/fix after the reversal has been completed.
