Where do push odds from in half pt calculator?

Looking at the half pt calculator, I'm wondering where the push odds come from, are they historical?

If so, I'm guessing that it's been a very long time since any game had a total points line of 4 in the MLB, since that comes up with a zero chance of push.

The smallest total I have ever seen in MLB is 6.

They are historical data from covers.com I believe.

The calculator lets you put in your own percentages if you like.

the problem with putting in your own percentages is if you push anything it seems to reset them
