You just got two great "opposite sides of the coin" perspective. I have lived with a bookie (my grandfather was a bookie) and gamblers, so I have seen both sides too. I think since you are not taking bets (of course that is illegal in most US states
) and are the punter then you need to look closely at Biz's comments, they are excellent methods for developing your own "systems"/angles. Lt Dan is right, but the books can't account for EVERY angle and situation, but they will move to close loopholes when they can, which is why you need to adjust and find new ones or the gaps that open up when the books do adjust.
I think Biz is right that the betting market is a free market and as such is becoming a very efficient one, you can see this in the returns on some models/methods over the last 5 yrs vs the 5 yrs prior. But the books will inherently always have an advantage because of juice/vig etc...the books models/understanding is getting better every year (NCAAB lines this year have been ridiculously good), but there will ALWAYS be places to take advantage.
If you are not going to build a full on regression model then Biz has the right process...
Bullet points for your process:
- Pick the sport you know the most about (I am talking 'understanding' of the game, players, strategies etc...) [ you can add others later, but start here]
- Think about the type of wager that you think your knowledge could assist (spread, ML, total, 1H)
- Find a solid online database of data that you can query (there are 3-5 reputable ones which are anywhere from free to fairly pricey to a novice bettor)
- Sit down and brainstorm some ideas that you think could generate an edge (e.g., the team with the greater number of shots wins in NHL - not true, just an example lol)
- THEN test the ideas - be reasonable if you tweak it.
Don't get data and build models from the data, there has to be a 'cause and effect' just cherry picking data does no good. This is the place where most people fall down. They find great %'s historically but they are meaningless. Statistics only truly work if there is a grounding for the concept. Just because a two game ATS losing streak gives a 98-2 record, doesn't mean a thing unless you have a legitimate reasoning for it
- Looks for systems that have
at least 60% winners, at least 70-100 data points, consistent performance (look to see nothing less than an approximately break-even season). The higher the number of data points and the higher the % that is the trick. Look for 'tighteners' to improve returns without destroying your game count etc...
- Try to find systems that don't overlap too much (conceptually different...you might have one based on penalty minutes, one based on shots on goal, one based on Road Dogs, totals based on goalie save% etc....)
- How many plays do you want to be playing each day? I am comfortable playing 20-30 games each day to bring the statistics in my advantage (need large numbers), others prefer much fewer plays that appear to be very high percentage winners....a very personal decision
- Rinse, repeat as necessary
Once you have your plays make sure you have a way to track them (excel, online databases etc...)
MONEY MANAGEMENT! Don't overplay your picks....statistics works on the laws of large numbers, you plays will be small numbers at first and you can get burned overplaying them.
Don't post them on a forum until you have done at least some of this work. If you do and they are not fully vetted yet, make a statement to that effect so that new forum viewers can tell the confidence in them, remember what you post could affect someone else's money. It is their decision to play, but give them as much information as you can so they can make good decisions whether to follow you.
Hope this helps.
Best
