Informative thread we have here gents.

My answer(s) will be restricted as i am only back in "OZ',
For today flying back out again tonight.

When sorting out a selection(s) method whatever one it is,
I always do this.

You must adjust the number of selections for the field size you,
Are betting in, unless you have your own prices and set a cutoff figure,
At a certain price.

What use is checking the top 1-2-3-4 chances of a preferred method,
In say a field size of 5-6 runners.

This is the formula i used but you can adjust to your own specifications.

"FIELD SIZE"
=<8(1-2-3)
9-12( 1-2-3-4)
13=> (1-2-3-4-5).

Remember if you do your own pricing then you would probably have a set cutoff where over that price the selections are not profitable except possibly for the exotics etc.

For straight mechanical methods.
Openers.
P/Post.
Ratings etc, i use the field/size method.

This is just my way of sorting, others may be different.

Cheers.
