So, what are the metrics required for building a system? how could you use past draw information to pick future draws?

Fundamental questions to be sure, and considering what we try to do everyday, ones that need some attention.

I have come up with 4 tools to add to a draw profile, for each position in a pick3...

1.Count... show how many times 0-9 followed the currently drawn number throughout your selected draw history.

2.Day Of Month... based on the 1-31 range, shows 0-9 for the last draw on THAT day of the month, a filter... a subset of the data above.

3.Day Of Week... based on 1-7, so i can see what followed a 9, for example, every time a 9 came up on a tuesday...

4.Simple follower... if a 6 is picked tonight, and a 3 was picked last night, how do 0-9 look when the 3-6 chain is previously drawn.

now the question... which is more important? the one with the highest count? the one with the highest opportunities for a match?

I am developing a backtest that will check all 4 tools against the draw history to see if any could have been used for a winning system... found some glimmer of hope on the midday drawing using the day of the month, using just the MAX count it would have paid 5 straight hits in 2,200 draws, which on $1 st. would leave a profit of $300, currently... 

So much to do before even paper testing can begin...

So, what tools are in your system? (Notice I was not counting Even/Odd, Hot/Cold, Low/High... filters not used in a system where the end result is just one number).
