Hi Mark and Chuck
The horse should and usually does show something about its current form from the last line.
The nice thing about just looking at the 3 numbers, and the patterns of the horse, is you can see when the last line might fool the public.
Also we can trip handicap,
Here is horse 7 from today's last race a MVR
Here are the last lines for all the horses in the race.
Off the last line the top 5 are 5 2 11 7 1 (step 1 )
Now jumping right out at me is the late energy of line 1
or ,why did it use less energy early ?
The answer is a trouble trip.
It looks like the horse was swung wide . and then ran well to finish with its best ever LPR .
If we forgive this line and move to line 2, I can forgive it because of wrong surface (poly)
So now I go to line 3 . I already know horse 7 rates well off a trouble line
so I am happy to see it rate better off a good line.
The 7 wins at a nice price.
