Hi Brian
Thanks for your response, very nice of you to go into depth with this.
It´s good to get some clarity here to understand the difference between the kinds of sync.
I´d really wish that it was possible to optimize it further though. It might seem like a little thing, but if you use OmniFocus as your main tool during the day it´s a shame if there is even a slight feeling of resistance to use it.

I usually open Omnifocus (or any other list management app) at least 10 times per day. Since I switch between OF for Mac and OF for iPhone a lot during the day so I have to sync it almost every time I open the app on the iPhone.
If you compare it to an app like Remember the Milk, which is the app with the best and most intelligent sync I have seen, it takes in average 10 secs to sync at startup, and OmniFocus takes 22 secs in average to sync at startup.
That´s a difference of 12 secs. per app launch.

That means that it takes 2 minutes longer to sync OmniFocus per day, or a whole hour per month, or 12 hours per year. When you add it up it´s a long to have that spinning wheel on the screen.
