Ok, I haven't checked the actual numbers, but I was thinking this could be the best possibility, in a vacuum.
First it might seem that snaking 4s + 3-zoning 5s > 4-zoning both, but there is the additional 5 in the top zone, connecting that in rack 9 will make 4-zoning both more valuable. Anyhow, there isn't a big difference in score between these two. So if there is 45 in rack 8, it is about the same no matter how rack 7 is played, well not counting gambling with 4s, which I guess could be an option if we considering only winning. There is also an added bonus here, that if we can't snake 4s/5s in rack 8, we can actually play a 1 to an outer zone (right) leaving center without a 1 for rack 9. Or we could play 11 in rack 8 without losing bonus if we can't snake 4s/5s/6s. So we could get +2 bonus either way, which is more than enough to make up the small difference between 4s/5s even if the last rack 5 doesn't hit.
Playing like this leaves open snaking 4s with 44, 5s with 55, and even the miracle 666 to snake 6s. 55 is a huge bonus if it hits. 44 is the same as with others options, well other than 445 in some. And the miracle 666 open is nice as well, it will hit 4 % of the time!
What we don't want to see in rack 8: one 4 with no 5s; 22 isn't great either, but it might be ok if the chain dice with the 2s are suitable.
