Well, this is a snippet from variables.h:
Code
#define ResultLong		(g->statLong->Result)
#define ResultShort		(g->statShort->Result)
#define ThisPerformance	(g->w)
//#define DailyLong		(g->statLong->pCurve)
//#define DailyShort		(g->statShort->pCurve)
//#define DailyTotal		(g->pCurve)
So, obviously somebody at a time had the intention of using/exposing it; I doubt it is just taking up space for nothing.

Zorro calculates several stats for the Performance report/ in training that are based off bar-ly returns per component. Total portfolio Results are also calculated from asset/algo results.

Why not expose those to a user?
