3 Greens - "estimated 100'", but almost 1/2 mile laterally...no big deal for professional pilots...
Perhaps you'd better leave us professional pilots to decide whether we can judge such distances, closure rates, wake prediction and spacial awareness such that we dont endanger our passengers and aircraft and go and live to fly another day!
Oh, I should of added night to that list, but nah, after all, its no big deal!!!!!!!!
