W CA which is the shockwave between C and A is a backward recovery shockwave since the density at C is higher than the density at A ??

I think the shockwave from C-A should be a forward recovery shockwave because C has higher density and A has lower density. The traffic condition is going from high to low density will be considered as recovery. Also the slope is positive which will be considered as forward.
