On my posted pics (first MLB pics of the season posted today, a sweep!) I usually post this with it:
"all flat bet 1 unit risk per pic (for example, a +135 pic would pay 1.35 units, a -135 pic would pay 0.74 units, no rounding up or down).
no SU chalk over -170."
I don't like to vary my bet, by even a little bit, because then my breakeven percentage will rise. If I take some really big ones, then why even take the smaller ones?
Yes, this flat-bet method of risking same amount on every bet means that payoff on big faves not so big. But if I lose one of these shockers--then, hey, I'm just down one flat-bet amount. That helps keep the emotions on even keel, which you need for the day-to-day grind. And nice day if you win those big dogs!
In baseball I don't like to make one game more important than the next. Betting this sport is all about grinding out wins and finding value, not picking "winners". The worst teams are still gonna win 60 games.
Also this method easy to bet with in Las Vegas as you place simple $20 or $200 bets, or whatever, and force the ticket writer to make change on just the payouts. Also simple for the record keeping and comparisons--folks can grasp and scale easy for their own bet size what "Win/loss is 100-64, up 32 units for season" means for them in real dollars winnings and outlay at ticket counter.
"flat-betting" means wagering in a manner that gives all games equal relative weight. Technically, my way spelled out above doensn't do this. Risking same amount on each bet regardless of odds, I'm actually putting more weight on games that are farther away from +100; my +180 and -170 games have more value than my -120 and +120 games. I don't mind that as I usually scruitinize those high favs or high dogs more anyway, and I wanna keep my method because of all the benefits listed. And I don't take too many high favs or high dogs anyway.
But to give true equal weights to all bets (be technically correct in "equal weights"), you take your unit amount (1 in this example), and bet the amount that the risk + the win = double the unit size.
For example:
-120 fav: risk .91 to win 1.09
+150 dog: risk .80 to win 1.20
-200 fav: risk 1.33 to win .67
+180 dog: risk .72 to win 1.28
For a Fave: Bet Size = 2U/((100/ODDS) + 1)
For a Dog: Bet Size = 2U/((ODDS/100) + 1))
where U = Unit Size and ODDS = the absolute value of the odds, or the odds without the negative sign in front if there is a negative sign.
That said, I do some scaled wagering, two-star pics at 1.5 units and such. Mostly to get the flexibility to really take advantage of prime gambling situations, when I thinks one pic is real strong or when I'm on a winning streak. Tho I'm not all convinced in long run this works for me. But helps my gambling emotions and hunches, and fools me into thinking I can grow my bankroll faster RIGHT NOW. But I don't post them here, but sometimes capture their value by adding to a parlay, like today.
