By request, posting regular updates of this at another site. If there's continued interest here as well, I can do the same.
The usual disclaimer: 2nd half data doesn't include overtime simply because I find tracking to be more accurate this way.
Also, I'd be cautious with this data. I think oddsmakers have not only caught up but are perhaps even overcompensating for some teams now. Plus, betting is driving numbers even higher in some situations. The other night, in the Utah/Denver game, the game total was around 187. The first half total was around 89. The second half total opened around 96 at some books and, per usual for Utah games, quickly rose, peaking at around 99/99.5 at some books. The 2nd half score was 55-42. Utah was a strong 2nd half over team earlier in the season, but just 10-10 O/U-wise in their last 20 games.
New Jersey is another example. They were similar to Utah earlier in the season. Their 2nd half number still regularly soars. Tonight vs Sacramento, it opened around 97/97.5 and peaked around 100. The 2nd half score was 42-40. They've been mostly a 2nd half under team since the coaching change, possibly due to inflated totals.
Washington also falls into this category. Tonight's 2nd half total vs NY opened around 100.5/101. It reached 105.5 at one book I monitor with the consensus sitting around 104. It went over but only due to overtime. The regulation score was 49-47.
As can be seen, away/home seems to affect some teams' records drastically.
