It's not very hard to estimate a good spot if you take in information from many sources, such as watching the speed and direction of cloud shadows, how slow you're moving across the ground on jump run, etc. More than once I've observed us crawling across the ground on jump run and taken the spot out another quarter mile or so. I don't mind having the winds aloft forecasts available, but there are many other sources of info for your spot estimates.
Back when we all jumped rounds you got immediate and obvious feedback on every spot. Now with square canopies it's really not as critical unless you're the guy who has to go find cutaway canopies in the woods.
