I see deceleration as the flip side of early speed. A horse can post a big EPR but if its deceleration is high its vulnerable when pressured. Low deceleration horses are often reliable finishers.
High deceleration a horse used up its energy early and tired late.
Low deceleration a horse distributed its energy more evenly and finished stronger.
I personally never use deceleration as a stand alone. I always include v/dc, total energy and %med.
I will say that Mitch is more of an expert on this than i am. I know that his past postings have helped me tremendously.
Mitch and LT1 are subject matter experts in this area.
