From the Synergism graphics displayed by David and the pace lines that were used by FTL,I would conclude that this race would run a slow 3 pace. Not withstanding, we all have our ways of picking pace lines. Pace line selection is subjective.
can we rely on them ? Not always.
The race in reality ran a Fast 1
which indeed favored a sustained horse. The winner was a sustained horse.
As with most software I have seen, there is no perfection.
In that race, I used Energy and came up with the same horse as Ernie.
My pace line selection for this race might be considered as unorthodox.
They are not the same or near what Ernie used.
If I would have used Synergism 4, my projected outcome may have been different.
Here's the pace lines I used.
