Back in the day before everyone knew the secret to making the wing ball, racking for each other worked fine. You simply racked them as tight as you can and the guy broke.
Now that everyone knows the secret to making the wing ball, racking for each other makes no sense.
In this case, Jen B is in a "damned if you do, damned if you don't" scenario. If she takes the honest route, she is going to give you a perfect rack and expect a perfect rack in return. If she is giving you perfect racks and you are not returning the favor then she is going to request a million reracks, as she did.
Her other option is to accept your bad racks and then purposely give you less than perfect racks which is pretty shady b/c she is not racking the best that she could.
What do you expect her to do? Should she give you perfect racks while you give her bad racks?
I've been in this situation a million times. I know how to rack too well. Should I be at a disadvantage because my opponent isn't as good at racking as me? Should I intentionally not give my best rack? I usually end up just carelessly racking for my opponent and then accepting all of their racks just to avoid an argument. I'm not racking them loose by any means but I'm definitely not spending the time needed to give a perfect rack.
I would argue that my racks are, Atleast, adequate. On the 3 occasions that Jen had to rack, she had the same issues i did. The difference was that I don't really check the rack. The most I do is take a quick peak just to let the racker know that I might look and to encourage them to do there best, but I don't actually check the rack. I like to believe that my opponent oh honorable and if not, I'm usually not willing to argue about it.
