Greenup bias [TCKT11062013BIAS]
« on: 06 Jun 2013, 12:23 »
Hi,
Has anyone come up with a formula for a greenup bias favouring the shorter priced horse/player/team ?
By this I mean, showing all the profit on the fav and other selections showing break even. The general idea by my thinking is that there is no point having an equal profit on a selection that is 10 to 1 when the fav is at 1.05.
Any thoughts/suggestions ?

hi,

I am looking at the 'greenup-unequal-profit formulas and have shown them below

bm_laya*(1 + P*bm_layp - P)/(1 + P*back_price - P)         (lay and back)
The above one is to lay and use a back bet to greenup. This works effectively and requires the selection to win to make a profit or break even if it doesn't. What I would like to achieve is the other way around meaning if selection won then break even and if any other won then make a small profit.

bm_backa*(1 + P*bm_backp - P)/(1 + P*lay_price - P       (back and lay)
Similarly with this one above which uses a Lay bet to greenup and would like to again break even if the selection won or a small profit if another won.

Can anyone advise.
Many thanks

hi
you are trying to make something simple in to a complicated solution.
you are not using the triggers as they are supposed to be used, they are for LEARNING.
if you had used the triggers and tried to learn how they work and altered the settings, as you should be doing.
you would know that the triggers will do exactly what you want.
all you do is set the profit of the selection to 1 , this then reverses the profit/loss

Thanks mcbee,
It's useful in my opinion to have two running. One where you think your selection will win and the other where there is uncertainty (more than usual :))
Events where there are several entrants.
