Bluewolf,

I do hope that we can all kiss and make up and move on and enjoy this wonderful hobby, and present our views, all the more credibly, without personal attacks. ***
This is one of the things I already addressed. Maybe you thought it was just an attack with no basis in reality? Did you read the post script?
It is claimed that one null (point of tangency) can not be calculated from the other. According to the rules of geometry this is only possible if the cartridge can be aligned two ways at the same time. In other words, it's not possible. If you have an alternate solution I'd be interested.
