How possible is it that I simply ran well and achieved those extra 32 wins thanks to dumb luck?
Fortunately, since just about all of my picks are sides, it's basically equivalent to a coinflip. That is, if it were not for the house juice on both side, I would be paid even money for winning.
There are a few exceptions to this, such as picks where I get -115 instead of -110, as well as two or three -125/-120 type moneyilne picks, but I also had my share of -105 lines in there (which cancel some/all of those out), so I believe this is mostly negligible, and I will ignore it.
So the grand question becomes: In a "coin flip" situation where you're basically picking one side or the other, both of which pay the same, what are the chances of getting 87 out of 142 correct?
I ran this through a coin-flipping calculator and found that the chances are very small 0.18%.
This means that there's a 99.82% chance that I have achieved this NBA record through at least some degree of handicapping skill.
