Areas of Specialization for Graders

[pachyderm]

I have heard that modern bulk orders take more time as card from different sports or other classification have to be sent to different graders. Does anyone know how these are divided? Does basketball have a different set of graders from baseball? I suspect someone that mainly grades ultra-modern basketball would have difficulty authenticating a vintage golf card.

Also, would this affect turnaround times? If there are not many golf cards being submitted compared to the number of graders would the cards come back sooner?
