20/9 might be right, but if it is, not very much because it would have to go next turn anyway. For most numbers, playing from the 20 will not be blocked
All numbers that don't have a 6/5/4 in it are blocked, that's 9. [11 22 33 21 31 32] On top of that what if you make the ace point and roll a 62 or 53 next turn? So while 'most' numbers is true by definition, I don't think it's true by meaning.
I don't give much weight here to making points in order -- any 5 point board should often be useful.
Ugh. You can keep going with these examples but making your points in order is often a lot more important than people think.
