Publishing of the line horse on Tabonline

The identification of the line horse used by handicappers is key to figuring out how ratings in a race are achieved. For many years the line horse was not published by the handicappers and this has been criticised here and else where. For the last few months, the full race results on tabonline have contained a column identifying the line horse. Unfortunately in many races line horses are not identified, more than one line horse is used in a race, and to my eye, far too many 3rd placed finishers are marked as the line horse.
