VRP ??? Seems to favor the later portion of the ???TimeWindow???, why?

I am using the VRP solver to set up delivery routes with specific time windows out of a single depot.  When I review the results it appears that the VRP solver prefers to get the delivery to the location as late as it can, while still staying within the time window so as not to cause a violation.

Can anyone explain why I might be seeing this?  I have altered my routes' earliest and latest start times to try and get the deliveries out of the depot as efficiently as possible but the solver still seems to prefer using as much time as it can instead of getting things to their locations closer to the beginning of the time window.

Any and all help/advice is appreciated.
