Dabid sums it up pretty well
"Trying to understand the process by which Jehovah's Witnesses get their new understandings is quite a challenge. They claim to be directed by God and the Bible, but their teachings go in circles and seem to have no direction at all.
They should just confess that they have no idea what they are talking about, but instead they say that your life depends on obeying them and this weird direction that they supposedly receive from God."
