AFAIK they do it from final times 1L = 0.2s
If Smarty Runs 2.28.0 in Belmont and the second runs 2.28.8 the chart will read 4L.
As a sidebar, in reality at 1Length = 9ft...
12furlongs = 7920ft = 880Lengths
So for Smarty 1L in Belmont = 148secs/880L = 0.168secs
The real winning margin was 0.8secs divided by 0.168 gives 4.76 Lengths even though the chart will read 4L because they approximate 1L to 0.2s.
