What is the horizon for cumulative value in GOP and feasibility of promising against cumulative
GOP promises against the cumulative value .How far ahead or back does GOP go to calculate this cumulative value.
Secondly is it feasible to promise against cumulative because say I have not available supply today but 1 month from now I have supply of 10 and no demand then cumulative of 10 will show today but can I really promise against this supply?
