Robin’s advice is solid.
Your questions indicate a syndrome I refer to as “dancing on the edge.” Some also refer to this as taking calculated risks. I pretty consistently drive a little faster than the posted speed limit. I try to keep my speed within a range that I deem to safe enough to avoid a ticket. It usually works. I don’t get tickets often and I am willing to pay an occasional ticket to fulfill my “need for speed.”
When regulators find you dancing on the edge they may or may not cite a violation, but over time they form an opinion that your program is reckless, just barely in compliance and occasionally just barely out of compliance. If you can live with an occasional violation and a downgraded management rating in order to continue dancing on the edge, go for it.
If you want to avoid the occasional violation and restore your management rating set your LTV at 89% so you are unquestionably in compliance. Even a small miscalculation won’t send you tumbling over the edge, because you are dancing a safe distance away from the edge.
