distance decay function in invest

hi all,

a question on the pollination model. The distance decay function relates the contribution of each cell to an agricultural land parcel to the distance between that cell and an agricultural land parcel. The closer the cell the higher the contribution. In the inputs the average flight distance has to be provided. However, no maximum flight distance has to be provided. This means that in principle each cell in the landscape can contribute to an agricultural but this contribution can become infinitely small. Although it likely does not effect the results it might seriously increase computation.

I was wondering if it's possible to set somewhere in InVEST a predefined maximum flight distance or whether InVEST already uses a predefined threshold below which cells have no contribution and stops calculations?
