If there are 10 draws and 62 win/loss games, the conference would finish equal if the West won 35 and lost 27. In that case the West would have 115 points, the East would have 91 points, and the West will have gotten 55.8% of the remaining points. The reason this is different from what I underlined is that your 56.5% was neglecting that fact that wins and losses must be whole numbers. If you take 56.5% and multiply by the 206 points that East vs. West games would have if 10 of them are draws, you get 116.39. That's 117 when rounded up to the nearest whole number, but if 10 out of 72 East vs. West games are draws, it's impossible for the West to get exactly 117 points against the East. I rounded up because the if the West needs at least 116.39 points, 116 isn't enough. To provide a simple example, let's say Team X is done playing and has 1 more point and the tiebreaker over Team Y, who has 1 game left. Team Y needs a win to pass Team X. Team Y could pass Team X by getting 2 more points, but that's impossible to get from 1 game, so everybody will say "Team Y needs a win" rather than "Team Y needs at least 2 points." If there are 23 East vs. West draws, the West would need 9 more wins than the East to finish ahead of the East, with it being impossible to have the East and West have the same amount of points. In that case there would be 29 wins for the West and 20 for the East. The West would need to get 57.0% of the remaining points.
