Transportation of RNG

Hello,

I'm modelling a Wood Residue to RNG pathway and would like to know the effect of the finished fuel transportation distance (from plant to pipeline).

I've set Input!B45 (single site SCNG gen and use) to "No" and I've been manipulating Input!AX95 (Truck km of CNG), but I see no effect on the end results from the latter. Why is this?

Is there a different way to model this problem?

Thanks!!
