Consistent V40+ on practice, V38 on actual...

Hi everyone - looking for some words of advice and maybe encouragement here.

I just did my first official GMAT today and scored a 700 (Q47, V38). While I know this is a good score, I was aiming for a 720+ and had hit a 740 (Q48, V42) on the practice exam that I had taken one week before the official test.

My gripe is whether or not my Verbal level is actually 40+ or if it's just under 40. I've been hearing that the GMATPrep and Exam Packs are a little dated and do not represent the current state of the test. Is this true? Because I've been using these exact sources to gauge where I'm at. What's even worse is that I was feeling very confident when I finished the Verbal section (I selected my order as V, Q, IR/AWA), so I'm not even sure where I went wrong.

Below are my practice scores:
GMATPrep 1: 710 (Q47, V41)
GMATPrep 2: 710 (Q47, V40)
Exam Pack 1 Test 1: 710 (Q45, V42)
Exam Pack 1 Test 2: 740 (Q48, V42)
In addition to these scores, I had been getting V40+ on the last 3 CATs on Manhattan Prep as well. This is why I'm so shocked that I got a 38 on the actual.

I've already signed up for another exam in three weeks and will buckle down to do what I can to hit that 720+. PLEASE DO NOT tell me that this timing is bad or whatever, I've already signed up after all. I'm just looking for advice and insights here.

Thanks!
