IT IS GREAT TO BE CURIOUS!!
I'm so glad that you have an open mind!!
keep it open, work hard at this, grade plays, and over time you might just develop a consistent edge!!
the most important thing is money management, especially at first. if you lose your entire bankroll, no matter the size, that takes you out of the game. not only will you have no money to bet, the vast majority of people will lose interest and not watch lines and results at that point. so not only are you not making money, you are not learning or gaining experience either. death.
treat this as an investment, figure out a long term strategy. days do not matter, if they do, then your money mgmnt is faulty. weeks are somewhat significant, once you have an edge, then losing weeks are fewer than winning ones at volume. months are the real barometer. yes, you will have losing months, just as the books. but if you get to the point where you place 200 bets or more per month, and if you have an advantage, then this volume will illustrate the edge more often than not. if you have a losing month, so be it (at this point). the key is to isolate the reasons why. bad beats? bunch of favorites? less than 2 pt losses? on the majority of games I know whether or not I had the right side whether or not it wins. if I had the wrong side I try to isolate where my opinion was wrong. for instance: last night I lost on NO +5, MIA +5.5 1st, CLE +3.5 I would have taken all 3 all over again. NO is just in a funk, I figured they would snap out of it vs a Dal team that is not stellar on the road and plays no defense. didnt happen lost by 4. MIA +5.5 was an angle that I will use over time. NJ was just too 'hot' and it lost by 1.5. CLE I had at pick to -2, and it landed on pick. Unfortunately there is this ridiculous subset called overtime, and I lose well over 56% of OT games and having won the MIA/DET game even with OT I knew the outcome even with 42 seconds left in regulation before OT another 1.5 loss that would have hit had OT (which is not easily forecast) not have happened. Just one of those intuition things, and would I take all 3 again? yes. So I check myself, am I seeing clearly? yes, very. very few mistakes in the last few weeks. now looking at the winners from last night, were they right sides or benefit from close calls or luck etc? no. I look at how far the margin of victory ATS was. TOR over? not even close. LAC +7? SU with the nice ML. HOU -5? not close. the two 2nd half totals? TOR 4th under not as close as it landed but 2nd halves are generally dicey to begin with. CLE over? closer than it appears b/c of OT, but had it ended in 4, still a lot farther off than a lot of 2nd halves that I will win, obvious right side.
so were the total number of points that I won ATS by more than what I lost by, and per game? that is one of the things that I look at AFTER the game is over. A win is not a win.
