Deductions & credits

Hi, being in the same situation, I am interested in the unanswered part of the original question:

"Form 8938 requires 
maximum account value during year rather than amount year end, which makes the total account values really high. Let's say, Account A has $200,000 on October 1, Account B has $100,000. $100,000 is transferred from A to B, now Account A has $100,000 balance, Account B $200,000. The total for the accounts should be $300,000, but according to the reporting requirements it is now $400,000. Am I interpreting this right?"

In my case, due to some shifting of assets before transferring the whole to my US account, the total amount inflates the maximum account values by easily 100%. Do I manually change that to an estimate of the maximum value at my "richest point in time" during the year (which is bound to be somewhat tedious and difficult)?
