Tasks to Milestones

lyonel,

I am sorry that after reading your question 3 times, I still don't understand it.  Please re-phrase.

Between any arbitrary task and an arbitrary milestone (i.e. a zero-duration task), Project allows one of four relationship types and any amount of positive or negative lag.  ("Lead" in this context means negative lag.)  Which to chose depends on the real-world restraints you are trying to model.  There is no arbitrary solution.  As a rule linking to and from milestones causes no problems in Project's calculations.
