The 5 year rule - Living Overseas as UK Non Tax Resident

[ProfRogers]

Hi. Just so I understand the 5 year rule a little better for being a UK Non Tax Resident, I have created this simple example.
(We will presume in this example that I am correctly following the UK sensitive ties rules for spending the appropriate number of days in the UK.

So .... lets say I live 6 years overseas as a non UK tax resident, but I make a £1m Capital Gain EVERY ONE OF THOSE YEARS = £6m.
I then choose to RETURN to the UK on Year 7 as a tax paying resident. In theory would my CGT bill be £0?
