Not sure if this is the correct forum to post, but I thought it would be a good place to share the info.

With NBA coming up, I thought I'd share the chart I use to successfully middle NBA sides and totals. The first column shows the difference in spread/total, and the second column shows how often that middle hits. For example, if you have Team A -2 -110 and Team B +5 -110 [both for 1u], according to the charts you have a 24.41% chance of hitting the middle for a +EV of 0.41u.

For Sides:

0.0 2.28%
0.5 5.89%
1.0 9.73%
1.5 13.35%
2.0 17.53%
2.5 20.80%
3.0 24.41%
3.5 27.64%
4.0 31.25%

For Totals:
Difference Middle %
0.0 0.95%
0.5 3.35%

1.5 7.83%
2.0 10.00%

3.0 14.07%
3.5 16.81%
4.0 19.58%
