Thinking –

As part of this system is based on ratings, and the thinking behind ratings is that the more data you can gather, the more accurate the ratings will be, then maiden ratings will be less accurate and produce results that are poorer

Results –

Non-Maiden
Selections – 62
Wins – 23
Win % - 37.1%
Outlay – $62.00
Return – $75.80
POT - 22.3%

Maiden
Selections – 23
Wins – 9
Win % - 39.1%
Outlay – $23.00
Return – $31.00
POT - 34.8%

Justification –
As the ratings are free from the internet, I am unaware what data is used to come to the ratings. This may also explain why some of the other ratings performed so poorly. As the results show, there is very little difference between the 2 sets of data and as such, I would not use this filter in this particular case.
