I feel Race Rate would have to be one of the more genuine services out there.

They are not overpriced.
They don't use greed talk
They always state over what period there research was taken over.
They always state that there is no guarantee that it will repeat into the future.

What one is paying for, is the research that has been done, to discover a possible on going profit maker.
You may be able to make their angle more profitable using some of your own researched filters.

If you are interested in their Lay plan , one would have to check to see if their research was using TAB price or Betfair prices because there is usually about a 20% difference .
Therefore if results are based on TAB prices , one would need to see a minimum result of -30% LOT (profit to the Lay bettor) to allow for the 20% diff meaning 10% profit using Betfair, seeing that Lay betting can only be done on Betfair , it may appear strange why TAB prices were used instead of Betfair prices at 5 secs till jump or their SP .

So, if they report that their Lay system made 20% profit using TAB prices , that would mean , one would have broken even when Lay betting with Betfair due to the 20% diff in prices.

Here is a free data base to have a play with to kick things along.
Online System Builder (Google)
You can create your own Lay plan using this , one needs to create a plan showing a min of -30% LOT because TAB price are used instead of Betfair prices.

If you have a spare $5000 use GTX , considered to be the Rolls Royce of system builders, it can filter anything , even the horses colour.

Some have reported that Price Predictor producers a number of profitable systems .
They report , for some reason , it is easier to create a profitable system than when using GTX

If you are considering investing in a commercial data base , try & go for one that has a pre-post market included, this helps enormously in the filtering process.


Here's a Lay plan to get you started.
It works well on the UK Dogs as well as Horses.

RULES
Target TAB No.2 only.
Lay Price must be 3.60-5.60
20 secs till jump.
Bet 1% of bank level stakes.
Re-adjust bet if 30% is lost or won.

You are encouraged to place your own filters over the selection before making the Lay Bet.
