Yes.

Right [Begin - edit for clarification] "Earning from Taxable Account" is not 200K unless expenses equal 100K = pension income of 100K.for case #1 shouldn't E273/277 be $197,500 in order to get "100%" for details ?

but, for your example you want them to be 0% because it's all unrealized capital gains, no distributions?

sorry doesn't make sense, it must be you mean for all 197,500 to be taxable? ( I noticed that expenses somehow change the $1000k x 5% calculations, so it's not $200k

"Earning From Taxable Account" calculated as = [Taxable Acct Total Value + (Taxable Acct Total Value - net expenses)]/2 * 5% in this example.

So in case 1 zero "Earning from Taxable ACCT" is taxable because 100% of "Earning from Taxable ACCT" is due to share price increase, zero from distribution.

Or, 100% of "Earning from Taxable ACCT" (200K) is subtracted from total "earning+income" (200K + 100K), or in other words 0% of "Earning from Taxable ACCT" (200K) is taxable. [End - edit for clarification]
