The System Developer - Tip on Use
Use Proportional Staking
The most realistic picture of the true betting results from a particular history of selections is obtained by using the proportional staking method in the System Developer. This means that the bet size for each selection is based on either collecting a fixed amount or a percentage of the bank at the time.
The main reason for using proportional staking is that it eliminates the influence of long-priced winners, which can distort results and provide a misleading picture of the future prospects of those same rules. Using level stakes, longer-priced horses will have the same stake as shorter-priced horses. This means that the presence of a small number of long-priced winners in the past may have dramatically boosted your system results. However, simple statistical variance means that the chances of those longer-priced winners repeating at the same ratio in the future are far less than horses at the more fancied end of the market.
Level staking may also undersell the results that you could realistically achieve from your system rules. Having a level stake on longer-priced horses that would likely be ruled out of your betting plan with a sensible review of selections on a daily basis can drag down historical results, misleading you on what might actually be achievable.
To use proportional staking, make sure the option highlighted in yellow below is ticked
Ticking SP, NSW, QLD and VIC above means that the dividend used for winners will be the best of the starting price (SP) and three Tab dividends. This also provides the most realistic reflection of what you can achieve in the market. In fact, taking options like top fluctuation, best of the best or even smartly shopping for fixed prices on your bets can you see outperforming this result by a few percentage points.

A fixed target return means every bet is made to collect a set amount ($1000 in the example above) based on the starting price of the horse. A horse with an SP of $2.00 would have a $500 bet recorded by the System Developer, while a starting price of $10 would have a $100 bet recorded.
A variable target return (5% in the example above) means that each bet is made to collect 5% of the betting bank at the time. Using the $20,000 starting bank shown in the example above, the first bet would be made to collect 5% of that = $1,000, using the starting price. The result would be that bet would increase or decrease the bank size for the next bet and the new collect target would be 5% of that amount. This continues for each bet so that as the bank increase, the bet size will increase (as it might in real betting), but it always stays the same percentage of the betting bank (e.g. 5%). Equally, during periods where the betting bank is reducing, your bet size would also reduce, but remain the same percentage of the betting bank (e.g. 5%)
