The live version
The live arbitrage finder finds markets where the best prices across bookmakers make the book under 100%, with each stake worked out.
Worked example. Selections at 2.50, 3.50 and 4.00 with $100 to stake: the stakes are $42.75, $30.53 and $26.72. The book is 93.57%, so any one winner returns $106.87: +$6.87 when one of the three wins.
What it assumes. That exactly one of your selections wins if the bet succeeds. If none of them wins you lose the whole total, and a dutch covers only the selections you chose, not the whole market. With a book of 100% or more the equal return is no more than the total staked.

Spreading a total stake across more than one selection in the same market, sized so each returns the same amount if it wins. It is common in racing and in markets with many outcomes.
The arithmetic is the same. An arbitrage covers every outcome, so one of them must win, and profits when the book is under 100%. A dutch on only some outcomes can still lose everything if none of them wins.
Because the prices add to a book of 100% or more. The equal return is then less than the total staked, so the dutch loses at those prices whichever selection wins.
Two up to ten here. Adding a selection makes it more likely that one of them wins, but it takes stake from the others, so the return per winner falls.
