It would be great, however IRL you don't know the green speed until you chip or pitch onto the green.
I know the game gives us a lot of freebees wind speed, wind direction, putter pal, shot pal, but I beleive some things should remain unknown until you have the experience, that way it shows your ability to make adjustments to your game and become a better player. or you can play in your teir and always know the green speed for that teir
