Generally the answer is no .
If one bets every fav that moves.

So I used the UB System checker to see what it would reveal.

RULES
Good Track only.
Anything else & it shows a loss.

TAB No. 5-9
Anything less & it shows a loss.

Ran 1st-5th LS

Result
48% SR
39% POT


There were 38142 horse form lines in the database at this point in time.

There were 120 selections for the System
There were 57 Winners for the System for a strike rate of 47.5%
There were $167.05 returned for WIN (after 5% commission) which means a Profit or loss of $47.05 or a percentage profit/loss of 39.21%

This is only a starting point.
It needs to go through more data.


What is interesting is that when it comes to chasing profitable Favs , the track has to be rated nothing but Good.

Maybe someone out there has a larger data base to run this through.
