No, not us, and yes new to coverage in US.
We used to do the “putt path” that showed the optimal line in a video game style. But it got outdated and GC/NBC didn’t want to invest resources to modernize it. Only thing we do for golf (aside from the actual scoring of the event...lol) is the Drive Grid. Onsite we power almost all the video boards and digital scoring boards.
I kinda like the lines for the putt, but they should ease into it more. Take them out before the putt happens until people are more used to them. Every so often they won’t be accurate, and you can almost ALWAYS find a different way to make a putt on some of those greens. But, for the most part, they are pretty dead nuts. The program takes into consideration elevation, x/y/z of the entire route, and the time of day (and someone manually tells the program the speed of them at start of day) allowing it to adjust to grass growing opposite from morning (following sun) and how much faster it will be at a given hour.
