The first shot can be improved by pre-heating the group-head, I find, to do this I just put the cup I intend on using in place, then put an empty porta-filter in place and raise the lever.
This has the added benefit of warming the cup up as well.
Typically the first shot will be a bit blond, then shots 2/3/4 will pour a nice deep orange.
