Screwed by PMI for 1 credit point?

I am taking a mortgage for $266k and I am having a problem with the mortgage insurance.
My wife's credit score is 750+ but my credit is 719. Long story about why my credit is low but it is on the right track now, I know, I a little late now...
When applying for mortgage insurance, I am seeing a $60 difference between having a 719 and 720.

My lender told me about the difference and then I found this schedule: Won't let me post links, Google MGIC mortgage insurance, its the first PDF link.

We are in the 95% bucket with the PMI being .62% (720+) versus .89% (719-680).
Which is where the $60/month difference comes in.

We did a rapid rescore in an attempt to get another point but I am also worried that too many inquires is just going to lower it a few points (I had another lender do a hard pull the week before). Since Oct 2014, We've had about 5 pulls from going under contracts, pre-approvals, etc.

Is a rescore my only option?
Why are the bucketing differences so vast with a payment? .62% (720+) versus .89% (719-680).
One point is a .27% difference in monthly PMI payment, $60/month is a lot for me.

Am I missing other options for PMI?

I am having my credit pulled again next week to see if it is 720. Would it better to do it on Monday (3/30) or Friday (4/3)? I was thinking the credit unions would update month-end statements by Friday, as I have paid off my credit cards to low balances and paid a few student loans off

I suspect you aren't in the UK, so any answer given here would have limited significance.

We don't have credit scoring systems like other countries.

Yup you need a US based site, we don't use FICO scores or an equivalent here.
