In this video, health care bureau chief Brenton Flynn touches on the under-discussed subject of transparency in the data companies release in their quarterly earnings reports. While MAKO Surgical (MAKO.DL) has excellent transparency ratings in comparison with a company like Amazon (AMZN -1.65%), which is known for being a bit stingy with some of its data, there's one piece of MAKO data on Flynn's wishlist: vintage. Like a fine wine, Flynn not only wants to know how MAKO's surgical systems are being used now, he wants to know how they age over time, and how the utilization of the older systems stacks up against the newer ones. Seeing good numbers here would be good for investors and MAKO's clients, and that's good for everyone.
