Based on looking at the link and watching the video there it doesn't look like it would be all that accurate when it comes to providing club distance stats. It doesn't seem to account for "less than full" swings. Whatever clubs you select to punch out of trouble or use for less than full swing approaches to the green will have their numbers skewed.
For example, use your 5 wood to bump and run a shot next to a green and the distance it tells you your 5 wood will go is greatly reduced. Hit full shots 230 each of 4 times in a round and you average 230. Hit it 230 each of 4 times in a round plus a 20 yd bump and run and the system will tell you your 5 wood distance is only 188. Yes, that's what you averaged but that figure is no help in selecting the club for a future shot from the fairway. That figure also isn't very useful when analyzing your round to determine how well you hit each club.
I like the idea of the sensors but it should account for the creativity needed to play the game well. Not every shot is "grip it and rip it" . They need to expand on how much flexibility their 'dashboard" gives you when analyzing rounds and shots.
