So we were in the transition period for 3rd generation up till 2003 in Japan right? NES production in Japan 1983-2003.

Did you read any of my other comments up to that one?

Specifically the one about relevancy or sales?

"when no more systems are sold" You mentioned nothing of relevancy only sales. Nintendo still produced and sold NES till 2003 in Japan. So if you want to add another stipulation to dismiss the NES while counting the PS2 then so be it.

Fact is NES was in production for 20 years.

So do the final numbers for NES need adjusted or were all those produced units tracked?
