Just curious. Have you ever looked at what your record would be if you took the other side of your plays at the closing number? You tend to predict market value and get the best of each line at a high clip, rarely moving against you.
Not really. I know I have run unusually unlucky the last ten years in that regard though. Meaning, while I have won slightly more games (which I am not complaining about and quite frankly deserve) as a result of my good numbers from Sunday-Tuesday, it isn't as good as it should be (which would mean fading myself at close would not generate profit - though a breakdown on the big movers would be interesting to see). My bad numbers have come into play a lot the last decade. I can recall one week with 14 bets where I had the best of it in 11 and the worst of it in 3 and won zero as a result of my good number and lost two as a result of my bad number. Unfortunately for me, the number just hasn't mattered as much as it should. And while I used to devote more time to this to have time to track such things, these days it is all i can do to get my bets in and track the results segregated by sport.. I can't really spend a bunch of time doing a bunch of metrics on my stuff. The other thing that I would have to do is go back through and determine whether I would have played a game at the closing number or not for a different metric.
For my purposes, it really is just a way I can see if I am doing this well. As long as the lines/totals move the way I think they should on a consistent basis then I know I am capping the games right or noticing value right. That should be enough to give me confidence to keep going (though it doesn't take much for me to consider stopping nowadays because 1 bad week and I start thinking about not wanting to give back the profits with bets that decrease in value as the year progresses).
Something else that I perceive but have not tracked is my late adds as a result of steam seem to not have the value i think they do. For instance, say the first time I see Toledo/Umass number it is Toledo -11. I make the line 12,5. I pass on the game. It gets steamed to 14.5. I then take the game on the extra score. Those types of plays traditionally have done not so good for me (perception, I haven't tracked it). So in my mind, both my perception that my good numbers haven't mattered as much (land between close and line I bet) as I think they should and my perception that I have done bad when making plays when taking a side or total after it was steamed the other way, makes me think that following the steam isn't that bad even at the lesser number. I also know that books hate steam chasers (especially the ones who attack the books who are slow to move).
If I make a lot of bets and have a great year at 55% where I don't beat the close, I really don't feel like I would know whether I am making positive EV plays or not. If I make a lot of bets and have a not so great year at 49% and I consistently beat the close then I am fairly confident that I am playing with positive EV. So for me, the tracking vs the close is a way to know whether I am doing good work or bad work ..... I am doing good work this year (I am especially proud of my totals that seem to gradually move the way I would expect as the week progresses this year). Meanwhile I am having a good year with results too but if I didn't know what the games closed at, I really wouldn't know if the winning % is just short term luck/fluctuation.
Then you also have to be a bit locked into the market. Did I get line value (or lose line value) because of a trueish market or because of singular opinions...
Let me give an example.
ulm pickem vs idaho
Say drbob releases ulm as a play against idaho
his tailers slam into ulm
the line moves to ulm -2
the rest of the market is relatively indifferent to the game and small amounts of money are bet on this game because less people care about it, less people have quality info on each team, it is less likely to be a bet they can watch, etc. etc
So it closes ULM -2.
Two pts of line value but is it true line value? Because had drbob released idaho at pickem it would have closed at Idaho -2 and you would have two pts of line value that way too !!!!
So it is tough to know sometimes whether you are up against a true market (more likely in the heavy bet headliner games of the week) or just big money based on a singular opinion.
All of it is very difficult to ascertain from this side of the counter. So I just look at the aggregate for myself, for my purposes .... for just a general understanding of whether or not I am doing good work and playing with an edge.
Hope that helps as I realize I rambled and hit upon a tangent or two
