Well it came out to 2065, missing the middle by almost 100 points ! I think Weds games were somewhat unusual Sac/ Milw about 44 over, LAL/ NO about 28 over, and 3 more games going over by about 20. No OT's either.
I think if you tracked this for a long trial, you'd find it falls much closer to the CRIS number. I can't imagine it going under by 100, but over by a 100 can happen with OT's. I wouldn't judge the middle value one just this day's result.
I suspect WW just adds up the totals lines and uses that number to start their salami, and CRIS has a sharper method.
