This is absurd. After commuting for 1 year less than a year I knew which track to go to for any of the trains I ended up on. And more importantly where to stand on the platform to be at a door when the train pulled in.
The idea that somehow it's unknown or occult knowledge as to which track to go to is silly, when they announce the track for the train over the PA, they sometimes say 'This is a track change', and the few hundred people who are on the platform already have to trample back up to the concourse and then back down to the new track.
You must be using the LIRR. Things are not as consistent on the NJTransit side if the house. I know with about 90% certainty which of two platforms to go to for my train. Sometimes, like Monday, they throw us a curve ball and board us on the other side if the concourse. Occasionally we even board on track 13 in the LIRR area.
