Good link to that thread... much good info in that one.
I would add, always keep mental notes of the nuts-and-bolts specifics of where you see deer, ie. what elevation, what kind of cover they are using, where they are headed,what time of day, aspect of the slope they bed and are feeding on, what they are browsing on, etc. Deer in a given area dont always follow a for sure cookie cutter pattern of where you will find them, but by keeping your eyes out for similar terrain, feed and circumstances, you will get a good idea of what to key in on when you come across a new potential area.
Another obvious, yet extremely important thing is to be completely set up and be ready to rock and roll as early as you can possibly see in the AM. Glass as quickly as you effectively can. Fast but still be methodical and thorough in the first hour of glassable light. Dont be afraid to get mobile if nothing is showing. They will be up and moving then, and there will be plenty of time for using the microscope method looking for pieces-parts later.
An ideal all-day glassing spot to me in hilly or mountain terrain is where you can discreetly pop up over a ridge in a couple of minutes and see a whole 'nother large good looking area, especially during the critical dawn and dusk hour.
Really glass an area over HARD when you find even just one deer. Even if nothing is visible around the one you can see at the time, keep checking back often to make sure the deer is not a lone ranger. They rarely are.
