Impressive.

Did you start your blog back up?

No. It is by invite only- it is a "private community" now only for a handful (of course you are welcome any time).

Why did you do that?

lots of reasons. I actually shut it down entirely, then brought it back as a private club after thinking it over.

the two biggest reasons though, were that I think I was experiencing some "observer effect" (doing things differently because I was concerned about my record) and I was spending a lot of time responding to emails and comments. Internet fame is not something I have ever craved. Not to mention, I get a fair amount of hate mail when I lose.

So I wanted to separate the wheat from the chaff. No idiots allowed.

Interesting. Do you know how many hits you were getting or how wide your audience was?

I hear you on the hate mail. I Just watching people react to Performify is proof enough for me about how fickle people are. Bettors need to learn to own their bets. I've followed others' advice before and sometimes it hasn't worked out for me. I didn't blame the person who advised me though. I know that ultimately it was my decision.

That's actually one reason that I haven't been totally gung ho about doing public write ups and that sort of thing. Sure, you're everyone's best friend while you're winning, but if you lose then you're the devil.

Re: My bets going back to November 09

^^ very true. But as you can see, I was winning, alot. Some people would jump in right before a loss and then cry about it. I told my readers that I was going to hit a losing streak eventually, and that I would not continue to win 11:1 like I was before 109. But they don't listen. Honestly seeing that Performity thread influenced me. What does he get out of it? Of course, he doesnt do very well, so I also stated he should hang it up. When I announced I was shutting it down, several people went apeshit... you would think they were paying me or something. Funny how quickly people get entitled to something.

I installed analytics and I was getting about 400 hits per day on average. But I just got added to the blogroll at a site, and I could see that I was about to start getting a lot more hits... so I just decided I did not want to go that direction.

Why don't they just learn to analyze fights on their own? I certainly think there's something liberating about the fact that I seem to be good enough at this to be able to rely on my own abilities to be profitable. (My last three events have all be negative though, so I'm starting to experience self-doubt. Both Marquardt and Torres fucked my shit up big time.) I would not want to have to rely on someone else for that.

That's quite a few hits just for one day. How did you initially advertise your blog? Did you not have any desire to turn it into a commercial venture and try to make some real money off of it?

Re: My bets going back to November 09

I never advertised it. I made a few threads on Sherdog and a few of my regulars hace Sherdog signatures with my blog... It was in my signature here, and i was added to the blogroll at mmamoneyline, for free in a link exchange. That is it. Word spreads fast when there is free shit on the internet.

Nah, I never cared about being a real website. It is just a free blogspot... I considered adding adsense to it, but I read up on it and don't think I could have made more than a few bucks a month. I would rather just have the ease of reading without the ads for that.

As for becoming a pay service, no. I never have considered that, and never will.

I totally agree... that is the whole allure. Don't get me wrong, if I could find someone I believed could beat a sport, I would coattail them for a while. But ultimately, you want the freedom of knowing YOU have an edge.

But some people are stupid, so what are you going to do.

As for your current negative variance, hang in there. I am trying to make more bets to let my edge play out. I recently bet on Strikeforce Challengers and WEC which I never used to bet. I don't know whether you have an edge or not, but I suspect you do. Keeping track like I do really helps me see exactly what I need to do. For example, all my losses came in on heavy favorites... so I am trying to bet as much on the smallish favorites as I do on the -300 guys...

Like always though, my whole philosophy revolves around minimizing negative variance to avoid going on tilt. I think people vastly overestimate thier own control over their emotions.

Hey guys, new here. Just checking out the place on Scientist's rec.

For a normal betting event, edge is usually defined as (Win %) / (Implied Win %) - 1. [Equivalently: Win prob * decimal odds -1] In this case, 0.82 / 0.70 - 1 = 0.171, so just over a 17% edge.

However, I am not sure how well this concept is applied to a long string of bets made with different odds. For example, I don't know exactly how you calculated your "average line", but at a minimum, you would want to be averaging the implied probabilities, not the moneyline odds or the decimal odds.

You lost me. . . Pretty much immediately. . .

SPX SPX SPX.Just take the odds they'll win divided the implied win % and subtract 1

If you bet 15 fights and the average odds of those 15 is -233 thats an implied win % of 70% then you take the % you are actually winning (ex: if you went 11-4 in the 15 bets) thats a win % of 73 % .Then you take .73 divid by .70 which is 1.04 then you subtract 1 from that which is .04 .So you have a 4% edge over the odds you are betting

got it now?Or maybe I dont got it

OK, let me clarify.

Suppose I see odds that suggest a fighter should have an 80% chance of winning (i.e. -400), but I am confident that he really has a 90% chance. Then my "edge" is: 0.9/0.8 - 1 = 0.125. So I have a 12.5% edge. This means that on average, for every unit I bet, I expect to see a 0.125 unit profit.

The reason that I said edge was an iffy concept to apply to a string of bets, is because if you have many bets made with different odds, it really matters which fights you are winning and losing. You could be showing a great average edge and still be hemorrhaging money.

And for "average odds", I think the problems are clear if you make two bets: one at -200 and one at +200, and try to average it to zero. That's why you would need to use percent odds, if you were going to do this at all.
