What you would be missing is you are only calculating the vig on a win.  You are not taking into account the vig you pay when the bet loses.<\/p>\n<p>\tLet us look at what happens if you have to pay the vig on every bet.<\/p>\n<p>\tYou bet $21 five times.  For random you can expect to lose the bet three times and win it two times.<\/p>\n<p>\tYou wager a total of $105 and collect a total of $100 losing $5 out of $105 wagered (5\/105=.0476).  The house advantage is negative 4.76%.  <\/p>\n<p>\tIf you place the bet for $20 five times.  For random you can expect to lose the bet three times and win it two times.<\/p>\n<p>\tYou wager a total of $100 and collect a total of $96 losing $4 out of $100 wagered (4\/100=.0400).  The house advantage is negative 4.00%.<\/p>\n<p>\tSo not only is a HA of 4.00% better than 4.76%, clearly it is better to lose $4 out of $100 than $5 out of $105.<\/p>\n<p>\tIf they only charge you a $1 vig up front on wagers over $20 up to $38, you can do better with a buy bet than a place bet for wagers over $24.  But the HA is still pretty high even then.  It becomes break even at $24.<\/p>\n<p>\tWhen you wager $24 + $1 five times, you wager a total of $125 and collect a total of $120 losing $5 out of $125 wagered (5\/125=.0400).  The HA is negative 4.00% which is the same as a place bet.<\/p>\n<p>\tAt $30 the HA drops below that of a place bet but it is still a high HA.<\/p>\n<p>\tWhen you wager $30 + $1 five times, you wager a total of $155 and collect a total of $150 losing $5 out of $155 wagered (5\/155=.0323).  The HA is negative 3.23%, a fairly high HA.<\/p>\n<p>\tOnce you get to $38 it drops even more.<\/p>\n<p>\tWhen you wager $38 + $1 five times, you wager a total of $195 and collect a total of $190 losing $5 out of $195 wagered (5\/195=.0256).  The HA is negative 2.56%.<\/p>\n<p>\tSo if you are going to make a place bet anyhow, it makes sense to make a buy bet once you want to wager from $26 to $38.<\/p>\n<p>\tIf you only pay the vig when the bet wins, then it is a good idea to buy the 5 or 9.<\/p>\n<p>\tLet us look at what happens when you only pay the vig when the bet wins.<\/p>\n<p>\tYou bet $20 five times.  For random you can expect to lose the bet three times and win it two times.<\/p>\n<p>\tYou wager a total of $100 and collect $98.  They take the $1 vig from your winnings the two times you win the wager.<\/p>\n<p>\tYou wager a total of $100 and collect $98 losing $2 out of $100 wagered (2\/100=.0200).  The house advantage is negative 2.00%.<\/p>\n<p>\tYou can reduce the HA even more if they let you wager $30 or better yet, $38 and still only collect $1 for the vig.<\/p>\n<p>\tFor $30, you wager a total of $150 and collect $148 (2\/150=.0133).  The house advantage is negative 1.33%.<\/p>\n<p>\tFor $38, you wager a total of $190 and collect $188 (2\/190=.0105).  The house advantage is negative 1.05%<\/p>\n<p>\t<img decoding=\"async\" src=\"http:\/\/i65.tinypic.com\/t6y241.png\" alt=\"\" \/><\/div>\n<\/div>\n<div class=\"migrated-reply\" style=\"border: 1px solid #eee;padding: 15px;margin-bottom: 15px;border-radius: 5px\">\n<p><strong>Posted by:<\/strong> Dr Crapology on September 30, 2016, 11:40 am<\/p>\n<div>Skinny, what a thorough well written analysis.

Happy to help.<\/p>\n<p>\tJust thought of another way to look at it.<\/p>\n<p>\tIf you place it for $35, it pays $49 and you get a total of $84 ($35+$49).<\/p>\n<p>\tIf you buy it instead, you buy it for $34 + $1 vig for the same $35 bet each time.  But the buy pays $51 and you get a total of $85 ($34+$51).<\/p>\n<p>\tThat might be an easier way for you to figure out which is the better bet.  I am only looking at the win.  But I am looking at it by betting the same amount as a place or buy.  Thus I have the same amount at risk for all my bets.  That is why I can look at just the win here.  When you looked at only the win wager you were looking at betting different amounts.  The bet can not be compared that way.<\/p>\n<p>\tThe reason I tell you this is because at higher amounts the buy bet may not be the better bet.<\/p>\n<p>\tFor example, $115 place bet pays $161 for a total of $276.  You could buy it for $110 + $5 vig for the same $115.  The buy would pay $165 giving you a total of $275.<\/p>\n<p>\tAt this level a buy bet is always worse than a place bet.<\/p>\n<p>\tFigure which pays more, the place or buy for the same amount to figure which way to go.<\/p>\n<p>\tYou can do it using dollars and cents even though that is not the way they would pay you to see theoretically which is the better bet.<\/p>\n<p>\tSay you wanted to buy it for $46 + $2 vig.  It would pay $69 for a total of $115.  A $48 place bet would pay $67.20 for a total of $115.20.  Here a place bet is better.  You need to get to $50 &#8211; $58 to make the buy bet the better bet.  That is because the buy at $48 + $2 vig pays $72 for a total of $120.  The place bet of $50 pays $70 for a total of $120.  At a $2 vig you need to bet $50 to make the buy bet the same or better bet.<\/p>\n<p>\tThus for a $1 vig you can buy it between $24 and $38.  But for a $2 vig the range is only $48 to $58.  The range narrows as you get to the higher amounts.  For a $5 vig the place bet is always better.<\/p><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve been getting heat on this.
