Proper traveler position and how to bring it back up is one of those things that is boat and condition specific. No absolutes.
I've raced and cruised a lot of multihulls. It is seldom useful to have the traveler above center, and is nearly always wrong in waves. In part this is because they are faster pointing a little lower, which is true of most shoal keel cruising boats as well. Also, because multihulls slow quickly in the tack, it is nearly always faster to drop the traveler (or ease the sheet) just a little and then squeeze it back in quickly after the tack. You will be back up to full speed faster than footing and then pointing. Also, for the singlehander using autotack, it is one less operation (no need to reset course, only to yank on one rope).
No absolutes. Experiment. Every boat I have owned, and every boat I have crewed on, had different "best ways." And it depends on the weather. My moderate-to-light procedure and my heavy air procedures are slightly different.
