Record from 3/10-4/3: 6-12

Overall NBA record to date: 179-159-6 (52.96%)

So that's a little above the 52.38% mark you need to have a profitable season, but not by much.

The season was a tale of two parts:

Through December 30: 98-62-2
December 31-April 3: 81-97-4

While this "break" is arbitrary (I purposely selected my peak and then started the second portion at my first real losing streak), it's clear that I was doing something very right in November and December, but stuck too long with an approach which wasn't cutting it in the middle and later portions of the season.

I did have some bad luck in the second portion of the season, getting a lot of unders ruined by OT (more than expectation), and taking a number of bad beats on spread games.

Also notable was HOW I was winning. In November and December, it was common for my picks to win by 20+ points (especially the unders). In 2018, my wins tended to be close. This is important because the blowout wins tend to indicate an excellent pick, while the close wins are more a function of luck.

I may or may not pick the playoffs. I'm mostly done for the regular season, unless something jumps out at me.

Next year I will take a different approach in January-April, and perhaps just shut it down if I start to slump, as it seems I'm just better at early season.
