OK, the track I was at has changed to the new NHRA reaction time reporting system. Nothing has changed regarding how a race starts, i.e. Sportsman tree is still 3 sequential lights .5 secs apart followed by a green .5 after the last light and Pro tree is 3 simultaneous lights and green following .4 secs later.
The new way of reporting R/T has a perfect light being .000, foul is -.001 or lower. Think of it as an "absolute" R/T. I think the reason they do it is to eliminate the "different" perfect R/T between Pro and Sportsman trees. It's simply a new way of showing R/Ts.
So, my .205 light is what would normally be called .705, the .151 was really a .651.
Cecil already started using it, and Englishtown said they would be using it before the season was over. I suspect many tracks (especially NHRA tracks) will be converting to it soon.
