Hi Spyhunter,

They are selections under the heading "Radio TAB" which is the service that broadcasts the race meetings every day on the radio. Accordingly these are their selections for winning that designated race. Three sometimes four selections for 1,2,3 and/or 4 are provided as they see it- simple as that. However when assessing each race if you were to take each selection provided under "Radio TAB" for 1st place and all the other runners in the race for 2nd place in an exacta (1st and 2nd in order) and vice versa you would be surprised at the number of times you select the winning combination.
