Okay.
Then you have my full approval Mattio.
I would suggest that you increase the Power number so that your Odds a stretched a little more.
It seems your top selections are being undervalued consistantly.
Increase the power Number an amount that shortens your top selections a little more.

Can't remeber exactly what it was , but ain't hard to find.
Something about the frequency of your selections winning is about your handicapping skills.
And the strike rate of your selections is about your Pricing Methods.

Nah - best I find the post.
I'll chuck it in the EDIT.

EDIT : Its actually in this thread
"Remember you need to measure your handicapping with Strike rate and Wagering with ROI."
