If that's the case that's not even close to the time needed to test a saddle.
Read this:
Initial adaptation: Supporting the weight of the trunk on the ischium does require a small adaptation, as the nerves in the skin under the bony surface must grow accustomed to the increased pressure felt on those areas. For most riders, this takes 3-12 days, depending on the weight of the rider, the mileage ridden, and how accurately the saddle is positioned. Once this adaptation happens, the saddle ‘disappears’ under the rider. Sometimes, this nerve pressure reaches a ‘crescendo’ of discomfort before adaptation occurs.
You've ridden it once @alialias?
