[vpFREE] Gender bounce back differences?

 

Has anyone else seen a difference in bounce back offers based on gender? My wife and I have only played at this property once and were playing the same game next to each other, we both ran a tinge over $30,000 through the machines and we both ended up within $100 of break even. Now her bounce back offers are double of what mine are (accounts are considered independent). Because of this weird fluke it seems that the only variable is gender, anyone know if all/many casinos give better offers to those players simply because they have two X chromosomes?
