Mardia's Christmas 2x Grinders

That's irrelevant - even if 80% of the 2000 people who are 100+ go inactive that's nothing compared to 10% of the 399,974 Mardians we have today. ( 1600 vs 40,000) and we know the number of low level abadnons is in excess of 30%

It's a lot easier to data mine 2,000 people than 400,000

I see your point.
