Nope.Afraid not hippiepool.It doesn't depend on that at all.How much money is wagered on any given player is irrelevant to calculating the "book percentage".
The book percentage is determined by calculating the sum of the winning odds of all the runners expressed as a percentage.If the sum comes to over 100% the overall cumulative odds of all the runners is in the bookmakers favour,if it comes to less than 100% (not often !) it is in the punters favour.The higher above 100% it goes the more the bookmaker is ripping off the punters with skinny odds.
Now a typical book percentage on a high volume online betting market,let's say a soccer world cup match, might be in the average range of 103% to 109%.
The book percentage on the bookmakers odds list in the first post in this thread is approaching 200% !!!!!! The book percentage on the new odds list above is almost exactly the same.
Now can you see what I mean?
