Super resource - I love that you can take a bunch of raw data and turn it into something genuinely useful.

Can I suggest an expansion of one of the features? That is Redeem or Buy ( with Companion Voucher ).

Appreciate that the ranking may not change and there's a bit of a complication with how many points the second person would earn depending on their status, so it probably means adding a second selector.

I've tried to do this myself on Excel but couldn't get the maths/logic to come up with the same figure as you - so I gave up!
