Unit System Basics
Like most gamblers I track my results using a unit system. Below is a brief synopsis of how such a system works.
What is a unit system?
A unit system is a means of measuring sports wagering returns and losses. A unit is equivalent to a dollar amount that is directly proportionate to a bettors bankroll.
How do I organize a unit system?
First you must decide how much you are going to invest in sports wagering. After that decision is made you should set your unit size = to a percentage of your bankroll. I almost always set it at exactly 1% of my bankroll. For example, if you are willing to risk $10,000 total for college hoops season than my unit size would be $100 or 1x =$100. Thus a 1x play would = $100, a 2x play would = $200, a 4x would = $400 ad infinitum.
How do I account in units?
I've always tracked my wagers based on what I am risking rather than what I am trying to win. Let's say you risk 2x (2 units) at standard juice (-110) on a game. If you win your bet than you gain +1.8x (1.8 units), if you lose your bet than you lose -2x (-2 units).
To find out how much real money you are up or down at any point in time just multiply your net unit gain/loss by your unit size. If you are up +10x for MLB season with a unit size of $100 then you are up $1000 (10 x 100) for the season. If you had set your unit size at 1% (1x=1%) then this gain would represent a 10% R.O.I. for the season.
What is the point of using a unit system?
There are many reasons to track your results in this manner:
- Calculation via units levels the playing field and allows for meaningful comparisons between gamblers at every point on the financial spectrum. For example lets say Rico has a $20 unit size and is up $200 for a season while Chuck has a $2000 unit size and is up $6000 for the year. Well, Chuck has certainly made more money than Rico, but technically Rico is having a much better year proportionately speaking as he is up 10x to Chuck's 3x.
- Units make accounting much easier. If you bet $5 or $10 a game you won't notice as much but trust me, once you start consistently having to account for lots of zeros you'll want an arbitrary unit of measure in place of actual dollars not only for ease of calculations but also for psychological reasons. Plus converting units to dollars involves nothing more than a little simple algebra. Net gain in units multiplied by the dollar amount of unit = net gain in dollars. Not that hard folks.
- Units also offer a degree of privacy. I hate to say it but most people inherently suck. They don't recognize gambling as anything other than a dangerous vice while simultaneously being nosy. If someone asks me how much I have riding on a game it is much easier to say 3 units than it is to say $X,XXX. I'd much rather get a look of a confusion rather than some nonsensical lecture from a random idiot about my "gambling problem".
Should I adjust my unit size as the season goes on?
There is no right or wrong answer here. Having a sliding unit scale certainly makes calculations a bit more complex and tedious. I personally have always waited until the end of sporting seasons to evaluate and adjust. For example let's say after football season my bankroll has grown from $10,000 to $12,000. In this instance I'd probably keep my unit size for basketball at 1%, but instead of being worth $100 my unit would now equal $120 due to the increased size of my bankroll. Sort of like quarterly compounded interest, I suppose.
My unit size is smaller than the other gamblers, Does this make me less of a man?
No son, but it probably means you are poorer. In all seriousness though don't worry about how much other people are betting. Most people who claim to bet big are either lying or betting more than they can afford. If you consistently win without spending your capital gains then you will be betting large shortly anyways.
