Why CPS 1010? that specimen doesn't appear in the hypodigm of Torvosaurus in Carrano et al. (2012) nor in that of Hendrickx and Mateus (2014).

El CPS 1010 es Edmarka rex, ese aparece en el trabajo de Bakker, 1992 en Hunteria. Además para más infomación se puede consultar 

Aún no se sabe si Edmarka rex es válido o sinónimo de Torvosaurus tanneri como lo sugiere Holtz, Molnar and Currie, 2004 y Carrano, Benson and Sampson, 2012 porque no hay un análisis detallado al respecto según cita Mickey Mortimer en su sitio Theropod Database aquí:…

Estaba conciente que aparece en el trabajo de Bakker, es solo que parece haber sido removido del hypodigma en practicamente todos los trabajos recientes que pense que ya no se creia parte de Edmarka rex, pero tienes razón respecto a la falta de un análisis detallado.

That name of Edmarka rex has swallowed into the "Torvosaurus rex."
If Edmarka rex really does turn out to be a Torvosaurus species, then there may actually be a ~12-meter Torvosaurus after all!

When I first read about Edmarka rex I thought it could had bee a close relative or maybe a subspecies. But shortly after Torvosaurus gurneyi was announced, I questioned the idea of it being a Torvosaurus species myself. So I'm glad I'm not alone in thinking so.
