I've never really taken any notice of dutch betting, but it occurs to me that you could use it to strengthen big overlays. Say you're backing you're overlays on your prices to take out a set price, would it be beneficial to then multiply them by a factor which would rise the greater the overlay?

Example race, say you're backing them to take out $100, for ease of maths:

A $3.00 rated price, $2.50 in market, therefore no bet.
B $5.00 rated price, $5.0 in market, you have $20 on it
C $5.00 rated price, $10.00 in market, you'd have $20 on it multiplied by 2, because it is double the assessed price.

Does this work, or does it end up the same in the end? Obvoiusly when a big overlay wins, you clean up, but you're outlay would rise overall too.

Thoughts?
