I don't understand how one can look at ROI vs. profit split, using the original stake to determine markup. The original stake is not marked up; the final package value (profit + stakeback) is. (EDIT: This isn't
really speaking accurately, but I do think it is what posters are trying to get at here)
Looking at the horse's cut vs. the initial stake doesn't speak to what markup represents. In a "I buy x% at y MU for $z" situation, it makes sense to look at the initial stake, since markup in that case is a function of it. But in a profit split, the horse's profit cut is a function of the final package value, not the original stake. Comparing his/her cut to the original stake doesn’t accurately show any relationship that exists in reality.
Since the horse has bought 0% of his action in the conventional sense, the horse’s MU can only be a function of the backer’s action, therefore it only makes sense to show the relationship as [horse’s profit cut] / [total profit + stakeback].
So, I wanted to take a look at the package provided by Duke (and the 2/20 package run by the same horse; since he didn’t show a breakdown I’m just assuming no refunds / unused buy-ins or rebuys):
March 4, 70/30 split—
Quote:
$194.73 horse’s cut / ($194.73 horse’s cut + $454.38 backers’ cut + $295 stakeback) = 20.626% MU (220% ROI)
February 20, 70/30 split—
Quote:
1723.62 ending bankroll
- 277.20 original stake
= 1446.42 profit
x .3 = 433.93 horse's cut
x .7 = 1012.49 backers’ profit
+ 277.2 stakeback = 1289.69 backer's cut
$433.93 horse's cut / $1723.62 ending bankroll = 25.176% MU (522% ROI)
Now, as for providing anything useful for backers prior to a horse’s run? I think we may still be SOL. I certainly think it’s possible for a stats-minded person to figure out a coefficient for expected ROI that takes into account the various variables at play.
So, since a horse’s markup is a % split minus stakeback, and assuming that the initial stake > $0, all we really know is that:
70/30 split: < 1.3 MU
80/20 split: < 1.2 MU
and so on…..
I’m not entirely sure about any of this, but there had been something bothering me for a while about BigVach's table on the last page so I thought I would try and flesh it out a bit. Any thoughts?
