This is an interesting discussion, but @Sundance, I disagree. I don’t think there’s much, if any benefit to the AHR Assurance program.
Amazon says -
With Account Health Assurance, we won’t deactivate your selling account as long as you work with us to resolve any issues.
This implies that there might be a case where you would otherwise get deactivated, and Amazon wants you to have AHA in order to avoid that.
I call BS. (I’d type it out but the forum software blocked me. 
)
I think Amazon’s insinuation is just a scare tactic.
First, violations don’t drain points from your account immediately. You are given a few days to ‘address’ the violations. If you address them, they disappear.
Amazon says ‘we won’t deactivate your selling account as long as you work with us to resolve any issues’. In what way is that any different than simply addressing the violations to make them go away??? The process - to me - sounds exactly the same, which means that AHA is worth absolutely nothing. 
Even if you did buy that it had value, you would have to anticipate doing something so wrong that you suddenly lost more (probably a lot more) than 50 points in one fell swoop. If you were that kind of seller, you probably wouldn’t have ever reached 250 in the first place.
My account lived perpetually ‘at risk’ in the days before the new AHR. I never gave it much thought, as every time Amazon told me I was doing something wrong, it was a BOT fk-up, and not a seller mistake. I didn’t feel it was a good use of time to continually ‘address’ stuff Amazon did wrong, so I just ignored it.
When I first got my AHR number, I was at a big, fat, red “12”. 
But not suspended. I clicked all the boxes to tell Amazon I wouldn’t do that again, and got 150 or so points added back immediately.
What I learned from watching the numbers change is that violations seem to go in increments of 8. Repeat violations doubled to 16. So you could have 1 violation (8 pts) plus 3 additional violations of the same thing (16 x 3 = 48), before you’d drop below 200, and even then, if you went from 250 to 194, you wouldn’t be at much risk.
I just don’t foresee a situation where the Account Health Assurance would provide any sort of help.
We woke up to 15 one day out of nowhere
Do you recall if any of them showed any ‘impact’ on your score? If not, they can be ignored. Also curious if the violations were on active inventory. I had a slew of inactive, long-ago sold products sitting in my inactive inventory because it had never been worth my time to delete them. I finally bit the bullet and went through and cleared them out, and now rarely get any violations any more.
What mine were mostly caused by was people who - in the good old days 
- created pages with random UPC codes, which trigger IP violations when Amazon checks if the UPC belongs to the brand name on the listing.
I 100% agree with @HobbesIsMyTiger. 
The only advantage of a higher number is that I have a larger cushion to absorb account dings that lower the score. However, I am working under the assumption that a larger volume of sales and items offered also exposes me to increased risks, and therefore the smaller seller barely hitting the minimum sales would have a commensurately smaller catalog and risk exposure.
It seems that whatever issues threaten our account also lower our score, but not every issue that lowers our score threatens our account.
And not every issue that threatens our account lowers our score either.
