Default Historical analysis for new betting system

This is my first post so bare with me!

I am researching a new system for sports betting. I am looking at a low risk minimal return stategy (over/under) looking at Amercian sports since they play lots of games everyday.

What sort of return on investment % (yield) figure would you think is decent and sustainable for a low risk minimal return strategy?

Also, without me doing much leg work... how much historical data should I be getting to to figure out if this is worthwhile pursuing? 100 games, 500, 1000+?

What do you mean by "low risk minimal return strategy" ?

The margin of error can be calculated from the formula 1/SquareRoot(No of Samples)

So if you had 100 games you margin of error would be +/- 10%
For 1,000 games this will drop to around +/- 3%
