Keeping up with the threads is practically a full time job, now I get where Jack calculates her 100 hour working week calculations.
Anyway, Mathsing.
Post cards come at the £7 tier, but I think it's a safe assumption that most subscribers are going to think it's worth paying the £3.50 up from the basic tier to get the goodies- post from your fav celebrity crook? bargain. She currently has 763 patreon subscribers, but that was up to 800 at some point.
Let's go with 750 just for simplicity. I know from my pals who have patreons (for cooking-related bits and bobs and actually deliver!) that most people will stump up the extra to get a physical object.
She has 6 tiers, so assuming an even split of patrons across all tiers, that's 83% of subscribers she'd need to do postcards for.
That's 622.5, let's say 622 people who need cards.
Rewards range from 3 to 10 cards depending on tiers.
3 postcards per person, that's between 1,866 and 6,220 cards a month she owes per month.
She hasn't delivered rewards since November 2020, which is 22 months.
Meaning she owes between 41,052 and 136,840 postcards.
I'm sure her local post office is thrilled by the news that during the postal strikes, Jack's going to be rocking up with her shopping trolley filled with tens of thousands of postcards and a shrug "ADHD amirght".
