I read a survey on a UK forum about the percentage of punter's betting preferences. I've often wondered, and here it is:

Backers.....50.1%
Layers.......11.5%
Each Way...21.8%
Place..........12%
Exotics.......4.6%

Straight away, Layers stand out as 2nd last taking their share of the pie. Now given that for every lay bet there's a matched back bet, and then there's those that place back bets with bookies and totes only (not the exchange), but are the layers matching more money per head than backers?

A rough example: For every 20 backers are there are only 10 layers but turning over twice as much money?
