After feeling bad about hijacking someone else's thread in this part of the forum I thought it would be best to start afresh.  I have something that I have been following for a while - a horse racing selection system.  I know, if you've seen one you've seen them all blah blah blah.  Well, prepare to be amazed haha!
So far there have been 265 selections between January 2017 and today, mainly around the weekends and big festivals etc..  Here are some stats:
Strike rate: 46%
Longest losing run: 9
Longest winning run: 6
Average WIN SP: 2.76 (Betfair: 2.88)
Point profit to level stakes: +71.76 (Betfair: +86.00)
 
I'm not going to say too much about the selection process - there are 8 base rules - but I will post the selections here.  The only rule you need to know is that the selection MUST START CLEAR FAVOURITE so having access to Betfair or whatever is essential to be able to watch the prices just before the off.  There will be cases where it's too close to call - in these situations I scrap the selection.
As for staking plans, this is where the aforementioned hijacked thread comes into play.  I am currently looking at some quite aggressive plans.
I have the following figures for the first 264 selections (all from a starting bank of £1000):
Level stakes (£10)
26.84% ROI - Current Profit £708 (Normal SP) - Total Staked £2640
32.23% ROI - Current Profit £850 (Betfair SP) - Total Staked £2640
Multiplier on loss (x1.2 previous stake)
25.21% ROI - Current Profit £858 - Total Staked £3405
Percentage bank (1% of bank always)
25.79% ROI - Current Profit £969 - Total Staked £3758
Square root (base stake of £10 plus the square root of the current bank minus start bank)
23.79% ROI - Current Profit £3052 - Total Staked £12831
1-3-2-6 Staking (based on a 1% stake)
27.36% ROI - Current Profit £2803 - Total Staked £10246
Ratchet (1% of current bank increasing over time but never reducing)
26.02% ROI - Current Profit £1017 - Total Staked £3909
Ratchet square root (combination of two above methods)
24.88% ROI - Current Profit £4028 (Normal SP) - Total Staked £16193
27.39% ROI - Current Profit £4873 (Betfair SP) - Total Staked £17794

Incidentally, selection 265 also won but I can't be bothered updating all those figures! 
The plans I will be following on here are:
Level stakes (for control purposes)
Square root
1-3-2-6
Ratchet square root
I'll be posting the selections below as I find them and also running totals.  I'll keep the above totals going but I'll also start from £1000 again for the purposes of this thread so we can all follow it together.  Sometimes there will be conditions for the bet such as 'only qualifies if there are at least 5 runners' or 'only qualifies if xxx is a NR' etc.  Finally I've attached a graph showing how some of the plans have performed.  Hopefully things will continue in a similar manner.
Last thing to say... I'm posting these selections for information only and I can't take any responsibility for losses that might occur from errors or otherwise.  Past performance is not an indicator of future performance for any system!  Let's go!

@thecurlyone1 I have pursued it tbh. The rules were never clear had a go may have another go when I get more time.

As it looks like the original poster has gone spending his 450k 
 
 

For it to work with under and over I think we will need all those options.  Have a look at these examples and let me know if I've understood you correctly:
Over 2.5 goals - You want to bring back all matches where the home team scored at least 2 goals and conceded 1 in their last x number of games and where the away team has scored at least 1 goal and conceded 1 goal in their last x number of games.  You'll need to set the home scored minimum to 2 and maximum to the highest number available (let's say 10).  You'll need to set the home conceded minimum to 1 and the maximum to 10.  For the away team, their min/max scored will be 1 and 10.  Conceded will be 1 and 10.
Under 2.5 goals - You want to bring back all matches where the home team scored no more than 1 goal and conceded no more than 1 in their last x number of games and where the away team has done the same.  You'll need to set the home scored minimum to 0 and maximum to 1.  You'll need to set the home conceded to the same.  Then do the same for the away team.
So, it looks like we'll need the eight options to cater for over 2.5 (set the min to the desired number and the max to 10 for both teams) and under 2.5 (set the min to 0 and the max to the desired number for both teams).  If we just have an 'average number' scored/conceded for each only matches where the average is exactly that will be returned - I highly doubt any matches will be returned as they'll have several decimal places due to the calculations.
Please correct me if I'm wrong - I'm struggling a bit with this one to be honest.

@duckmaster Been trying similar myself on low scoring games with lucky 15's and closely matched teams.

@keef75Amazing amount of work and a great job you have done.

@keef75 coming along great guns all we need is data now current season data is crucial here using pervious data is suicidal as Manchester United would vouch for on Sunday. 
 
Personally all my bets are inplay these days I don't bother pre match but using the data you are supplying could help me use inplay as well as my data I use from my site 
 
Keep up the good work and effort pays off for them who put the effort in
