NBA home teams in the playoffs....

NBA home teams in the playoffs.... Anyone figured this up? I've thought for years that anyone that had the balls to bet the money line and\or the spread on the home team throughout the playoffs would never lose. How have they done so far? I haven't kept up because I haven't placed a bet since the NCAA Championship game.
Favorite in Rd 1 has covered 25 of 37, 67% in Rd 1.
Thanks guru. It would figure that I would pick this month to take my longest break from betting in about 10 years.
