It`s possible to make money on time based system if you are disciplined and self controlled punter. I did it for 20 years .
1- The time based systems are not a confident bets , unless , classy horse in the field
2- The time based system works well in the country races or weak metropolitan races
-------------------------------------------------------
1- You need a data of the course records for every distances
2- Make sure the records of the distances are not depended on one horse race record
-------------------------------------
To make it very simple . i use these methods.
The winner of 1200 meter race time was -----1,10,
The horse lost the race by 6 length [ without the steward records ] the time will be --------11,00
3- To make it very simple again . I use these methods
50 meters----------3
100 meters---------6
150 meters---------9
200 meters---------12
An example
1200 meter race , Let`s say the winning time was 1,10,54 , Now , what time would be the finishing times. if the race was longer than 1200 meter race .
-------------------------
1200 m -----1,10,54 times
1250 m----- 1,13,54----------------adding 3-----10+3=13
1300 m----- 1,16,54----------------adding 3-----13+3=16
1350 m----- 1,19 54----------------adding 3------16+3=19
1400m------ 1,23,54----------------adding 3------19+3=23
I will continue later on . Any questions ?
