Ummm, it doesn't Have to....and sometimes it doesn't return for a re-test.
However, for some reason I reckon price does return more than 50% of the time, sometimes twice, in what is described as a secondary test.

I guess at some point I will have to tell the story of the little boy scout who jumped the creek (Bob Evans Style....)
(BoB Evans as part of Wyckoff Associates, which eventually became the Wyckoff institute, made up little stories as an aid to understanding some of Wyckoff's theories......with the boy scout story probably being the most famous)
